2012-04-05: Barry Smith The official OBI definition, explaining the meaning of a class or property: 'Shall be Aristotelian, formalized and normalized. Can be augmented with colloquial definitions' is terrible. Can you fix to something like: A statement of necessary and sufficient conditions explaining the meaning of an expression referring to a class or property. Alan Ruttenberg Your proposed definition is a reasonable candidate, except that it is very common that necessary and sufficient conditions are not given. Mostly they are necessary, occasionally they are necessary and sufficient or just sufficient. Often they use terms that are not themselves defined and so they effectively can't be evaluated by those criteria. On the specifics of the proposed definition: We don't have definitions of 'meaning' or 'expression' or 'property'. For 'reference' in the intended sense I think we use the term 'denotation'. For 'expression', I think we you mean symbol, or identifier. For 'meaning' it differs for class and property. For class we want documentation that let's the intended reader determine whether an entity is instance of the class, or not. For property we want documentation that let's the intended reader determine, given a pair of potential relata, whether the assertion that the relation holds is true. The 'intended reader' part suggests that we also specify who, we expect, would be able to understand the definition, and also generalizes over human and computer reader to include textual and logical definition. Personally, I am more comfortable weakening definition to documentation, with instructions as to what is desirable. We also have the outstanding issue of how to aim different definitions to different audiences. A clinical audience reading chebi wants a different sort of definition documentation/definition from a chemistry trained audience, and similarly there is a need for a definition that is adequate for an ontologist to work with.

OBO foundry unique label
An alternative name for a class or property which is unique across the OBO Foundry.
The intended usage of that property is as follow: OBO foundry unique labels are automatically generated based on regular expressions provided by each ontology, so that SO could specify unique label = 'sequence ' + [label], etc. , MA could specify 'mouse + [label]' etc. Upon importing terms, ontology developers can choose to use the 'OBO foundry unique label' for an imported term or not.

preceded by
x is preceded by y if and only if the time point at which y ends is before or equivalent to the time point at which x starts. Formally: x preceded by y iff ω(y) <= α(x), where α is a function that maps a process to a start point, and ω is a function that maps a process to an end point.
An example is: translation preceded_by transcription; aging preceded_by development (not however death preceded_by aging). Where derives_from links classes of continuants, preceded_by links classes of processes. Clearly, however, these two relations are not independent of each other. Thus if cells of type C1 derive_from cells of type C, then any cell division involving an instance of C1 in a given lineage is preceded_by cellular processes involving an instance of C. The assertion P preceded_by P1 tells us something about Ps in general: that is, it tells us something about what happened earlier, given what we know about what happened later. Thus it does not provide information pointing in the opposite direction, concerning instances of P1 in general; that is, that each is such as to be succeeded by some instance of P. Note that an assertion to the effect that P preceded_by P1 is rather weak; it tells us little about the relations between the underlying instances in virtue of which the preceded_by relation obtains. Typically we will be interested in stronger relations, for example in the relation immediately_preceded_by, or in relations which combine preceded_by with a condition to the effect that the corresponding instances of P and P1 share participants, or that their participants are connected by relations of derivation, or (as a first step along the road to a treatment of causality) that the one process in some way affects (for example, initiates or regulates) the other.

<fgf8a^ti282a> is_allele_of the 'danio rerio fgf8a' gene locus.
A relation linking an instance of a variable feature (aka an allele) to a genomic location/locus it occupies. This is typically a gene locus, but a feature may be an allele of other types of named loci such as QTLs, or alleles of some unnamed locus of arbitrary size.
Domain = allele Range = genomic locus (but in practice it is common to use a punned gene class IRI as the subject of this relation).
Note that the allele <fgf8a^ti282a> is not necessarily an instance of the danio rerio fgf8a gene class, given that we adopt the SO definition of genes as 'producing a functional product'. If the <fgf8a^ti282a> allele is nonfunctional or null, it is an allele_of the danio rerio fgf8a gene class, but not an instance (rdf:type) of this class. It would, however, bean instance of a 'danio rerio fgf8a gene allele' class - because being a 'gene allele' as defined in GENO requires only occupying the genomic position where for a gene, but not necessarily producing a functional product.
To allow users to make important distinctions in discourse and modeling, GENO clearly separates the notions/levels of 'biological sequence', 'sequence feature', and 'sequence location' ('genomic locus' when found in a genome). This sets up an important terminological nuance when it comes to alleles, where we believe it correct to say that a particular genomic feature is an alleles_of some genomic locus (as opposed to an allele_of some sequence or some feature). This is typically a gene locus, but even insertions falling outside of genes are considered alleles_of the locus they alter (e.g. alleles of other types of named loci such as QTLs, or alleles of some unnamed locus of arbitrary size). While conceptually it is most correct to say features are alleles_of some genomic locus, it is common practice to say that they are alleles of the class of feature defined to reside at that locus (typically a gene). Accordingly, we may write things like "fgf8a<ti282a> is an allele of the Danio rerio fgf8a gene", and we may create data where fgf8a<ti282a> is asserted as an allele_of the fgf8a gene class IRI. But here we mean more precisely that it is an allele of the locus at which the fgf8a gene resides. Allowing for this means that we dont have to create 'feature-based location/locus' terms mirroing all feature class terms already in exiistence (e.g. for every gene). It is important to be clear that the location/locus that a feature is an allele_of is defined exclusively by its genomic position, and not on the sequence it may contains. This is particularly relevant when considering transgenic insertions. For example, this means that the insertion of the S. cerevisiae GAL4 gene sequence within the D. melanogaster Bx gene locus would create an allele of the D. melanogaster Bx gene, but not an allele of the S. cerevisiae GAL4 gene. The transgene that results from such an insertion, while expressing S. cerevisiae GAL4 gene sequence, is not an allele of this gene because it does not reside at the S. cerevisiae GAL4 locus. This departs from how some databases use the term 'allele' - where transgenes expressing an exogenous gene are considered to be alleles of the exogenous genes they carry. For example, in the example above, Flybase describes the S. cerevisiae GAL4 transgene as an allele_of the S. cerevisiae GAL4 gene (and gives it the allele identifier FBal0040476). A GENO representation on the other hand would say that the S. cerevisiae GAL4 transgene derives_sequence_from the S. cerevisiae GAL4 gene, but is not an allele_of this gene. In a GENO model, FBal0040476 would be typed as a transgene insertion, but not considered an allele_of the Scer\GAL4 gene. At the end of the day, it's just semantics, but worth clarifying given the ubiquity and variable use of the term 'allele'. The GENO model attempts to define and adhere to the principled notion of positionally-defined 'alleles', and functionally-defined 'transgenes'.
A relation linking a gene class to one of its sequence-variant alleles.
Domain = punned gene class Range = allele
A relation that holds between an instance of a geneetic variation and a genomic feature (typically a gene class) that is affected in its sequence or expression.
This class to organizes all relations used to link genetic variation instances of any type to genomic feature classes they effect. For example, is_allele_of links a gene allele instance to its gene class (genes are represented as classes in our OWL model). Such links support phenotype propagation from alleles to genes for Monarch Initiative use cases. Use of these properties effectively puns gene class IRIs into owl:individuals in a given rdf datset.
A relation between a genomic feature class (typically a gene class) and an instance of a sequence feature or qualified sequence feature that represents or affects some change in the sequence or expression of the genomic feature.
This is an organizational grouping class to collect all relations used to link genomic feature classes (typically genes) to instance of a genomic feature sequence feature or qualified sequence feature. For example, linking a gene class IRI to an instance of an allele of that gene class. Such links support phenotype propagation from features/variants to genes (e.g. for Monarch Initiative use cases)
A relation used to describe a context or conditions that define and/or identify an entity.
Used in Monarch Data to link associations to qualifying contexts (e.g. environments or developmental stages) where the association applies. For example, a qualifying environment represents a context where genotype-phenotype associations apply - where the environment is an identity criteria for the association. Used in GENO to describe physical context of materialized sequence features that represent identifying criteria for instances of qualified sequence features.
A relationship between a variant allele and the gene class it is an allele of.
is_variant_allele_of
An organizational class to hold relations of parthood between sequences/features.
has_sequence_part
is_sequence_part_of
A relation that holds between two sequence features at a particular genomic location that vary in their sequence. These features will have the same position when mapped onto a reference sequence, but vary in their sequence (in whole or in part).
This property is most commonly used to relate two different alleles of a given gene (e.g. a wt and mutant instance of the BRCA2 gene). It is not a relation between an allele and the class-level gene it is a variant of (for this use is_allele_of)
varies_with
A relation linking a qualified sequence feature to its component sequence feature.
In GENO we define three levels of sequence artifacts: (1) biological sequences, (2) sequence features, and (3) qualified sequence features. The identify criteria for a 'biological sequence' include only its inherent sequence (the ordered string of units that comprise it). The identity criteria for a 'sequence feature' include its sequence and position (where it resides - i.e. its location based on how it maps to a reference or standard) The identity criteria for a 'qualified sequence feature' include its component sequence feature (defined by its sequence and position), and the material context of its bearer in a cell or organism. This context can include direct epigenetic modification, or being targeted by gene knockdown reagents such as morpholinos or RNAi, or being transiently overexpressed from a transgenic construct in a cell or organism.
has_sequence_feature
A relation linking a sequence_alteration to the gene it alters.
obsolete_is_alteration_within
A relation between two seqeunces or features that are considered variant with each other along their entire extents.
completely_varies_with
A relation linking a sequence feature to the location it occupies on some reference sequence.
has_location
A role assigned to a sequence feature, collection, or genotype, e.g. serving as a 'reference' against with other sequences are compared.
The RO:0000087 (has role) property cannot be used here because its domain is explicitly constrained to independent continuants, and sequence features in GENO are generically dependent contnuants.

A (currently) primitive relation that relates an information artifact to an entity.
is_about is a (currently) primitive relation that relates an information artifact to an entity.
7/6/2009 Alan Ruttenberg. Following discussion with Jonathan Rees, and introduction of "mentions" relation. Weaken the is_about relationship to be primitive. We will try to build it back up by elaborating the various subproperties that are more precisely defined. Some currently missing phenomena that should be considered "about" are predications - "The only person who knows the answer is sitting beside me" , Allegory, Satire, and other literary forms that can be topical without explicitly mentioning the topic.

2009-11-10 Alan Ruttenberg. Old definition said the following to emphasize the generic nature of this relation. We no longer have 'specifically denotes', which would have been primitive, so make this relation primitive. g denotes r =def r is a portion of reality there is some c that is a concretization of g every c that is a concretization of g specifically denotes r
Consdier if this is the best relation for linking genotypes to the genomic entities they specify. We could use the more generic 'is about', or define a new 'specifies' relation that holds between ICEs and something it specifies the nature or creation of.

This property and its subproperties are being used primarily for the definition of GO developmental processes. The property hierarchy mirrors the core GO hierarchy. In future we may be able to make do with a more minimal set of properties, but due to the way GO is currently structured we require highly specific relations to avoid incorrect entailments. To avoid this, the corresponding genus terms in GO should be declared mutually disjoint.

This branch of the ontology deals with causal relations between entities. It is divided into two branches: causal relations between occurrents/processes, and causal relations between material entities. We take an 'activity flow-centric approach', with the former as primary, and define causal relations between material entities in terms of causal relations between occurrents. To define causal relations in an activity-flow type network, we make use of 3 primitives: * Temporal: how do the intervals of the two occurrents relate? * Is the causal relation regulatory? * Is the influence positive or negative? The first of these can be formalized in terms of the Allen Interval Algebra. Informally, the 3 bins we care about are 'direct', 'indirect' or overlapping. Note that all causal relations should be classified under a RO temporal relation (see the branch under 'temporally related to'). Note that all causal relations are temporal, but not all temporal relations are causal. Two occurrents can be related in time without being causally connected. We take causal influence to be primitive, elucidated as being such that has the upstream changed, some qualities of the donwstream would necessarily be modified. For the second, we consider a relationship to be regulatory if the system in which the activities occur is capable of altering the relationship to achieve some objective. This could include changing the rate of production of a molecule. For the third, we consider the effect of the upstream process on the output(s) of the downstream process. If the level of output is increased, or the rate of production of the output is increased, then the direction is increased. Direction can be positive, negative or neutral or capable of either direction. Two positives in succession yield a positive, two negatives in succession yield a positive, otherwise the default assumption is that the net effect is canceled and the influence is neutral. Each of these 3 primitives can be composed to yield a cross-product of different relation types.

BFO 2 Reference: In all areas of empirical inquiry we encounter general terms of two sorts. First are general terms which refer to universals or types:animaltuberculosissurgical procedurediseaseSecond, are general terms used to refer to groups of entities which instantiate a given universal but do not correspond to the extension of any subuniversal of that universal because there is nothing intrinsic to the entities in question by virtue of which they – and only they – are counted as belonging to the given group. Examples are: animal purchased by the Emperortuberculosis diagnosed on a Wednesdaysurgical procedure performed on a patient from Stockholmperson identified as candidate for clinical trial #2056-555person who is signatory of Form 656-PPVpainting by Leonardo da VinciSuch terms, which represent what are called ‘specializations’ in [81
Entity doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. For example Werner Ceusters 'portions of reality' include 4 sorts, entities (as BFO construes them), universals, configurations, and relations. It is an open question as to whether entities as construed in BFO will at some point also include these other portions of reality. See, for example, 'How to track absolutely everything' at http://www.referent-tracking.com/_RTU/papers/CeustersICbookRevised.pdf
An entity is anything that exists or has existed or will exist. (axiom label in BFO2 Reference: [001-001])

continuant
An entity that exists in full at any time in which it exists at all, persists through time while maintaining its identity and has no temporal parts.
BFO 2 Reference: Continuant entities are entities which can be sliced to yield parts only along the spatial dimension, yielding for example the parts of your table which we call its legs, its top, its nails. ‘My desk stretches from the window to the door. It has spatial parts, and can be sliced (in space) in two. With respect to time, however, a thing is a continuant.’ [60, p. 240
Continuant doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. For example, in an expansion involving bringing in some of Ceuster's other portions of reality, questions are raised as to whether universals are continuants
A continuant is an entity that persists, endures, or continues to exist through time while maintaining its identity. (axiom label in BFO2 Reference: [008-002])

if b is a continuant and if, for some t, cis continuant_part of b at t, then c is a continuant. (axiom label in BFO2 Reference: [009-002])

An entity that has temporal parts and that happens, unfolds or develops through time.
BFO 2 Reference: every occurrent that is not a temporal or spatiotemporal region is s-dependent on some independent continuant that is not a spatial region
BFO 2 Reference: s-dependence obtains between every process and its participants in the sense that, as a matter of necessity, this process could not have existed unless these or those participants existed also. A process may have a succession of participants at different phases of its unfolding. Thus there may be different players on the field at different times during the course of a football game; but the process which is the entire game s-depends_on all of these players nonetheless. Some temporal parts of this process will s-depend_on on only some of the players.
Occurrent doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. An example would be the sum of a process and the process boundary of another process.
Simons uses different terminology for relations of occurrents to regions: Denote the spatio-temporal location of a given occurrent e by 'spn[e]' and call this region its span. We may say an occurrent is at its span, in any larger region, and covers any smaller region. Now suppose we have fixed a frame of reference so that we can speak not merely of spatio-temporal but also of spatial regions (places) and temporal regions (times). The spread of an occurrent, (relative to a frame of reference) is the space it exactly occupies, and its spell is likewise the time it exactly occupies. We write 'spr[e]' and `spl[e]' respectively for the spread and spell of e, omitting mention of the frame.
An occurrent is an entity that unfolds itself in time or it is the instantaneous boundary of such an entity (for example a beginning or an ending) or it is a temporal or spatiotemporal region which such an entity occupies_temporal_region or occupies_spatiotemporal_region. (axiom label in BFO2 Reference: [077-002])
Every occurrent occupies_spatiotemporal_region some spatiotemporal region. (axiom label in BFO2 Reference: [108-001])

An occurrent that has temporal proper parts and for some time t, p s-depends_on some material entity at t.
p is a process = Def. p is an occurrent that has temporal proper parts and for some time t, p s-depends_on some material entity at t. (axiom label in BFO2 Reference: [083-003])
BFO 2 Reference: The realm of occurrents is less pervasively marked by the presence of natural units than is the case in the realm of independent continuants. Thus there is here no counterpart of ‘object’. In BFO 1.0 ‘process’ served as such a counterpart. In BFO 2.0 ‘process’ is, rather, the occurrent counterpart of ‘material entity’. Those natural – as contrasted with engineered, which here means: deliberately executed – units which do exist in the realm of occurrents are typically either parasitic on the existence of natural units on the continuant side, or they are fiat in nature. Thus we can count lives; we can count football games; we can count chemical reactions performed in experiments or in chemical manufacturing. We cannot count the processes taking place, for instance, in an episode of insect mating behavior.Even where natural units are identifiable, for example cycles in a cyclical process such as the beating of a heart or an organism’s sleep/wake cycle, the processes in question form a sequence with no discontinuities (temporal gaps) of the sort that we find for instance where billiard balls or zebrafish or planets are separated by clear spatial gaps.

(These terms are all, in the jargon of philosophy, phase sortals.) By using role terms in definitions, we can create a BFO conformant treatment of such entities drawing on the fact that, while an instance of professor may be simultaneously an instance of trade union member, no instance of the type professor role is also (at any time) an instance of the type trade union member role (any more than any instance of the type color is at any time an instance of the type length).If an ontology of employment positions should be defined in terms of roles following the above pattern, this enables the ontology to do justice to the fact that individuals instantiate the corresponding universals – professor, sergeant, nurse – only during certain phases in their lives.

An allele that varies in it sequence from what is considered the reference or canonical sequence at that location.
The use of the descriptor 'variant' here is consistent with naming recommendations from the ACMG Guidelines paper here: PMID:25741868. Generally, the descriptive labels chosen for subtypes of variant allele conform these recommendations as well, where 'variant' is used to cover mutant and polymorphic alleles.
Note that what is considered the 'reference' vs. 'variant' sequence at a given locus may be context-dependent - so being 'variant' is more a role played in a particular situation. A 'variant allele' contains a 'sequence alteration', or is itself a 'sequence alteration', that makes it vary_with some other allele to which it is being compared. But in any comparison of alternative sequences at a particular genomic location, the choice of a 'reference' vs the 'variant' is context-dependent - as comparisons in other contexts might consider a different feature to be the reference. So being 'variant' is more a role played in a particular situation - as an allele that is variant in one context/analysis may be considered reference in another. A variant allele can be variant along its entire extent, in which case it is considered a 'sequence alteration', or it can span a broader extent of sequence contains sequence alteration(s) as part. And example of the former is a SNP, and an example of the latter is a variant gene allele that contains one or more point mutations in its sequence.
The reference/wild-type cd99l2 danio rerio gene allele spans bases 27,004,426-27,021,059 on Chromosome 7. The "mn004Gt" represents an experimentally-created allele of this gene, in which sequence from a gene trap construct containing an RFP marker has been inserted at the cd99l2 gene locus. The resulting gene allele includes sequence from this construct that make it longer than the reference gene sequence, and also alter its seqauence in a way that prevents it from producing a functional product. The sequence extent of this cd99l2 gene allele is determined based on how its sequence aligns with that of the canonical gene and surrounding sequence in a reference genome. http://useast.ensembl.org/Danio_rerio/Gene/Summary?g=ENSDARG00000056722 https://zfin.org/ZDB-ALT-111117-8
A genomic feature that represents one of a set of versions of a gene (i.e. a haplotype whose extent is that of a gene)
Regarding the distinction between a 'gene' and a 'gene allele': Every zebrafish genome contains a 'gene allele' for every zebrafish gene. Many will be 'wild-type' or at least functional gene alleles. But some may be alleles that are mutated or truncated so as to lack functionality. According to current SO criteria defining genes, a 'gene' no longer exists in the case of a non-functional or deleted variant. But the 'gene allele' does exist - and its extent is that of the remaining/altered sequence based on alignment with a reference gene. Even for completely deleted genes, an allele of the gene exists (and here is equivalent to the junction corresponding to the where gene would live based on a reference alignment). This design allows us to classify genes and any variants of those genes (be they functional or not) as the same type of thing (ie a 'gene allele'), since classification is based on genomic position rather than functional capacity. This is practical for representation of variant genotypes which often carry non-functional versions of a gene at a particular locus. What is important here is specifying what is present at a locus associated with a particular gene, whether or not it is a functional gene or not.
http://purl.obolibrary.org/obo/SO_0001023 ! allele
In SO, the concept of a 'gene' is functionally defined, in that a gene necessarily produces a functional product. By contrast, the concept of a 'gene allele' here is positionally defined - representing the sequence present at the location a gene resides in a reference genome (based on sequence alignment). An Shh gene allele, for example, may be a fully functional wild-type version of the gene, a non-functional version carrying a deleterious point mutation, a truncated version of the gene, or even a complete deletion. In all these cases, an 'Shh gene allele' exists at the position where the canonical gene resides in the reference genome - even if the extent of this allele different than the wild-type, or even zero in the case of the complete deletion. A genomic feature being an allele_of a gene is based on its location in a host genome - not on its sequence. This means, for example, that the insertion of the human SMN2 gene into the genome of a mouse (see http://www.informatics.jax.org/allele/MGI:3056903) DOES NOT represent an allele_of the human SMN2 gene according to the GENO model - because it is located in a mouse genome, not a human one. Rather, this is a transgenic insertion that derives_sequence_from the human SMN2 gene. If this human SMN2 gene is inserted within the mouse SMN2 gene locus (e.g. used to replace mouse SMN2 gene), the feature it creates is an allele_of the mouse SMN2 gene (one that happens to match the sequence of the human ortholog of the gene). But again, it is not an allele_of the human SMN2 gene.
A sequence that serves as a standard against which other sequences at the same location are compared.
The notion of a 'reference' in GENO is implemented at the level of 'biological sequence' rather than at the level of a sequence feature - i.e. we define a class for 'reference sequence' rather than reference sequence feature'. This is because it is at the *sequence* level that features of interest are determined to be variant or not. It is taken for granted that the *location* of the feature of interest is the same as that of the reference sequence to which it is compared, becasue an alignment process establishing common location always precedes the sequence comparison that determines if the feature is variant.
A reference sequence is one that serves as a standard against which 'variant' versions of the feature are compared, or against which located sequence features within the reference region are aligned in order to assign position information. Being 'reference' does not imply anything about the frequency or function of features bearing the sequence. Only that some agent has used it to serve a reference role in defining a variant or locating a sequence.
An allele whose sequence matches what is consdiered to be the reference sequence at that location in the genome.
Being a 'reference allele' is a role or status assigned in the context of a specific dataset or analysis. In human variation datasets, 'reference' status is typically assigned based on factors such as being the most common in a population, being an ancestral allele, or being indentified first as a prototypical example of some feature or gene. For example, 'reference alleles' in characterizing SNPs often represent the allele first characterized in a reference genome, or the most common allele in a population. In model organism datasets, 'reference' alleles are typically (but not always) the 'wild-type' variant at a given locus, representing a functional and unaltered version of the feature that is part of a defined genomic background, and against which natural or experimentally-induced alterations are compared.
A gene that originates from the genome of a homo sapiens.
A transgene that has been integrated into a chrromosome in the host genome.
An integrated transgene differs from a transgenic insertion in that a transgenic insertion may contain single transgene, a partial transgene that needs endognous sequences from the host genome to become functional (e.g. an enhancer trap), or multiple transgenes (i.e. be polycistronic). Fiurthermore, the transgenic insertion may contain sequences in addition to its transgene(s - e.g. sequences flanking the transgene reqired for integration or replicaiton/maintenance in the host genome. The term 'integrated transgene' covers individual transgenes that were delivered in whole or in part by a transgenic insertion. An 'integrated transgene' differs from its parent 'transgene' in that transgenes can include genes introduced into a cell/organism on an extra-chromosomal plasmid that is never integrated into the host genome.
An attribute inhering in a feature that is designated to serve as a standard against which 'variant' versions of the same location are compared.
Being 'reference' is a role or status assigned in the context of a data set or analysis framework. A given allele can be reference on one context and variant in another.

A structurally or functionally defined component of a transgene (e.g. a promoter, a region coding for a fluorescent protein tag, etc)
A sequence feature (continuous extent of biological sequence) that is of genomic origin (i.e. carries sequence from the genome of a cell or organism)
This class was created largely as a modeling convenience to support organizing data for schema definitions. We may consider obsoleting it if it ends up causing confusion or complicating classification of terms in the ontology.
1. A feature being 'of genomic origin' here means only that its sequence has been located to the genome of some organism by alignment with some reference genome. This is because the sequence was originally identified in, or artificially created to replicate, sequence from an organism's genome. 2. The location of a genomic feature is defined by start and end coordinates based on alignment with a reference genome. Genomic features can span any size from a complete chromosome, to a chromosomal band or region, to a gene, to a single base pair or even junction between base pairs (this would be a sequence feature with an extent of zero). 3. As sequence features, instances of genomic features are identified by both their inherent *sequence* and their *position* in a genome - as determined by an alignment with some reference sequence. Accordingly, the 'ATG' start codon in the coding DNA sequence of the human AKT gene and the 'ATG' start codon in the human SHH gene represent two distinct genomic features despite having he same sequence, in virtue of their different positions in the genome.
genomic feature
One of a set of sequence features known to exist at a particular genomic location.
A landsacpe review found mostly gene-centric definitions of 'allele' that represented a particular version of a gene, or variation within a gene sequence [1][2][3][4][5][6][6a]. But we also found 'allele' used to refer to other types and extents of variation - including single nucleotide polymorphisms, repeat regions, and copy number variations [7][8][9][10][11], where such variations don't neccessarily impact a gene. To be maximally accommodating of how this term is used across research communities, GENO defines 'allele' broadly and allow alleles can span any locus or extent of sequence. While 'alleles' encountered in public datases typically overlap a gene, many do not. But GENO does define the 'gene allele' class as a subtype of 'allele' to refers more specifically to a specifc version of an entire gene.

variable feature
An allele is a seqeunce feature at a genomic location where variation occurs (i.e. where >1 different sequence is known to exist). An allele can span only the extent of sequence known to vary (e.g. a single base SNP, or short insertion), or it can span a larger extent that includes one or more variable features as proper parts (e.g. a 'gene allele' that spans the extent of an entire gene which contains several sequence alterations). Alleles can carry 'reference' or 'variant' sequence - depending on whether the its 'state' matches that considered to be the reference at that location. Alleles whose state differs from the reference are called 'variant alleles', and those that match the reference are called 'reference alleles'. What is considered the 'reference' state at a particular location may vary, depending on the context/goal of a particular analysis. A 'sequence alteration' is a 'variant allele' that varies along its entire extent (i.e every position varies from that of some defined reference sequence).
An allele of a gene that contains some sequence alteration.
A gene allele is 'variant' in virtue of its containing a sequence alteration that varies from some reference gene standard. But note that a gene allele that is variant in one context/dataset can be considered a reference in another context/dataset.

'Sets' are used to represent entities that are typically collections of more than one member. But we allow for sets that contain 0 members (an 'empty' set) or 1 member (a 'singleton' or 'unit' set), consistent with the concept of 'mathematical sets'. Sets may also include duplicates (i.e. contain more than one member representing the same feature). The notion of a 'complement' is a special case of a set, where the members necessarily comprise an exhaustive collection of all objects that make up some well-defined set. It is useful for defining many biologically-relevant sets of sequence features. For example, a 'haplotype' is the set of all genetically-linked alleles on a single chromosomal strand at a defined location - e.g. the SNP alleles {rs7412-C, rs429358-C} comprise the haplotype defining the APOEɛ4 gene allele [1]. And a 'single locus complement' is the set of all alleles at a specified location in a particular genome - e.g. the APOEɛ4 and APOEɛ4 gene alleles ([1], [2]) that make up the 'Gs270' APOE genotype [3]. [1] https://www.snpedia.com/index.php/APOE-%CE%B54 [2] https://www.snpedia.com/index.php/APOE-%CE%B52 [3] https://www.snpedia.com/index.php/Gs270
sequence feature set
A set of genomic features (i.e. sequence features that are of genomic origin).
In some cases there may be zero or only one member of such a complement, which is why this class is not defened to necessarily have some 'genomic feature' as a member.
A genomic feature is any located sequence feature in the genome, from a single nucleotide to a gene into an entire chromosome. 'Sets' are used to represent entities that are typically collections of more than one member - e.g. the set of chromosomes that make up the human genome. But we allow for sets that contain 0 members (an 'empty' set) or 1 member (a 'singleton' or 'unit' set), consistent with the concept of 'mathematical sets'. For example, a 'single locus complement' at an X-linked locus in a XY male will consist of only one allele, as there is only one X-chromosome in the genome. Note also that sets may contain duplicates (i.e. more than one member representing the same feature). For example, a homozygous 'single locus complement' is a set comprised of two of the same feature. The notion of a 'genomic feature set' differs from that of a 'genomic sequence set' in that we are counting how many copies of the same *sequence feature* exist in a genome, as opposed to how many of the same *sequence*. 'Genomic feature sets are useful for representing things like 'single locus complements', where members are sequence features whose identity is dependent on their location. By contrast, 'genomic sequence sets' are useful for describing things like 'copy number complements', which are concerned only with how many copies of a sequence exist in a genome, regardless of the location where these reside.
genomic feature set
A genomic feature that is part of a gene, and delineated by some functional or structural function or role it serves (e.g.a promoter element, coding region, etc).
A sequence feature or a set of such features.
GENO defines three levels of sequence-related artifacts, which are distinguished by their identity criteria. 1. 'Biological sequence' identity is dependent only on the ordering of units that comprise the sequence. 2. 'Sequence feature' identity is dependent on its sequence and the genomic position if the sequence (aligns with definition of 'sequence feature' in the Sequence Ontology). 3. 'Qualified sequence feature' identity is additionally dependent on some aspect of the physical context of the genetic material bearing the feature, extrinsic to its sequence and its genomic position. For example, its being targeted by gene knockdown reagents, its being transgenically expressed in a foreign cell from a recombinant expression construct, its having been epigenetically modified in a way that alters its expression level or pattern, or its being located in a specific cellular or anatomical location.
sequence feature or set
A linear ordering of units representing monomers of a biological macromolecule (e.g. nucleotides in DNA and RNA, amino acids in polypeptides).
GENO defines three levels of sequence-related artifacts, which are distinguished by their identity criteria. 1. 'Biological sequence' identity is dependent only on the ordering of units that comprise the sequence. 2. 'Sequence feature' identity is dependent on its sequence and the genomic location of the sequence (this is consistent with the definition of 'sequence feature' in the Sequence Ontology). 3. 'Qualified sequence feature' identity is additionally dependent on some aspect of the physical context of the genetic material in which the feature is concretized. This third criteria is extrinsic to its sequence and its genomic location. For example, the feature's physical concretization being targeted by a gene knockdown reagent in a cell (e.g. the zebrafish Shha gene as targeted by the morpholino 'Shha-MO1'), or its being transiently expressed from a recombinant expression construct (e.g. the human SHH gene as expressed in a mouse Shh knock-out cell line), or its having been epigenetically modified in a way that alters its expression level or pattern (e.g. the human SHH gene with a specific methylation pattern).
'Sequences' differ from 'sequence features' in that instances are distinguished only by their inherent ordering of units, and not by any positional aspect related to alignment with some reference sequence. Accordingly, the 'ATG' translational start codon of the human AKT gene is the same *sequence* as the 'ATG' start codon of the human SHH gene, but these represent two distinct *sequence features* in virtue of their different positions in the genome.
biological sequence
In the VMC model, the notion of a GENO:biological sequence is called the 'state' of an allele.
A sequence feature (or collection of features) whose identity is dependent on the context or state of its material bearer (in addition to its sequence an position). This context/state describes factors external to its inherent sequence and position that can influences its expression, such as being targeted by gene-knockdown reagents, or an epigenetic modification.
qualified sequence feature or collection
Consider wild-type zebrafish shha gene in the context of being targeted by morpholino MO-1 vs morpholino MO-2 in separate experiments. These shha genes share identical sequence and position, but represent distinct instances of a 'qualified sequence feature' because of their different external contexts. This is important because these qualified features could have distinct phenotypes associated with them (just as two different sequence variants (alleles) of the same gene can have potentially different associated phenotypes).
A qualified sequence feature that carries sequence derived from the genome of a cell or organism.
qualified genomic feature
This axiom is an initial attempt to formalize the identity criteria of an extrinnsic context that separates qualified sequence features from sequence features (i.e. the context of its material bearer). As we further develop our efforts here this will get refined and more precise.
Formalizes one identity criteria of the sequence feature component of a qualified sequence feature (which itself is identified by its sequence and its genomic position).
A set of qualified sequence features that carry genomic sequence.
Because there are cases there may be zero or only one member of such a set, this class is not asserted to necessarily have some 'qualified genomic feature' as a member.
A 'complement' refers to an exhaustive collection of all objects that make up some well-defined set. This notion is useful for defining biologically-relevant sets of sequence features. For example, a haplotype is defined as the set of all genetically-linked alleles on a single chromosomal strand at a defined location - e.g. the SNP alleles {rs7412-C, rs429358-C} comprise the haplotype defining the APOEɛ4 gene allele. A complements may contain 0, 1, or more than one members. For example, the complement of alleles at a defined locus across homologous chromosomes in an individual's genome will consist of two members for autosomal locations, and one member for non-homologous locations on the X and Y chromosome.
qualified genomic feature set
An attribute describing a type of variation inhering in a sequence feature or collection.
variation attribute
biological sequence unit
An attribute, quality, or state of a sequence feature or collection.
Sequence feature attributes can be 'intrinsic' - reflecting feature-level characteristics that depend only on the sequence, location, or genomic context of a feature or collection, or 'extrinsic' - reflecting characteristics of the physical molecule in which the feature is concretized (e.g. its cellular context, source of origin, physical appearance, etc.). Intrinsic attributes include things like allelic state, allelic phase. Extrinsic attributes include things like its cellular distribution and chromosomal band intensity.
The location of a sequence feature as defined by its start and end position on some reference coordinate system.
1. A sequence feature location is defined by its begin and end coordinates on a reference sequence, but it is not identified by a particular sequence that may reside there. The same location, as defined on a particular reference, may be occupied by different sequences in the genome of organism 1 vs that of organism 2 (e.g. if a SNV exists within this location in only one of the organisms). 2. The notion of a sequence feature location in the realm of biological sequences is analogous to a BFO:spatiotemporal region in the realm of physical entities. A spatiotemporal region can be 'occupied by' physical objects, while a genomic location is 'occupied by' sequence features. Just as a spatiotemporal region is distinct from an object that occupies it, so too a genomic location is distinct from a sequence feature that occupies it. As a more concrete example, consider the distinction between a street address and the building that occupies it as analogous to the relationship between a genomic locus and the sequence feature that resides there.
sequence feature location
An engineered region that is used to transfer foreign genetic material into a host cell.
Constructs can be engineered to carry inserts of DNA from external sources, for purposes of cloning and propagation or gene expression in host cells. Constructs are typically packaged as part of delivery systems such as plasmids or viral vectors.
engineered genetic construct
An generically dependent continuant that carries biological sequence that is part of or derived from a genome.
An abstract/organizational class to support data modeling, that includes genomic features, genomic feature complements, qualified genomic features and their complements, as well as genotypes that denote such entities.
genomic entity
The location of a sequence feature in a genome, defined by its start and end position on some reference genomic coordinate system
In GENO, the notion of a Genomic Location (aka Genomic Locus) plays the same role as that of a FALDO:Region in the design pattern for describing the location of a feature of interest. We define this specific GENO class because the ontological nature of FALDO:Region class is not clear in the context of the BFO and SO-based GENO model. We will work to resolve these questions and ideally converge these concepts in the future. We don't link a Genomic Location to a specific reference sequence because in the FALDO model (which GENO adopts with the exception of swapping GENO:Genomic Locus for FALDO:Region), allows the start and end positions of a region to be defined on separate reference sequences. So while a given Location is conceptually associated with a single reference, in practice it can be pragmatic to define start and stop on different references sequences.
In practice, GENO advocates describing biology at the level of genomic features - i.e. define specific terms for genes as genomic features, and not duplicate representation of the loci where each gene resides. So we might define a class representing the human Shh gene as a 'genomic feature', but not parallel this with a 'human Shh gene locus' class. The utility of the 'genomic locus' class in the ontology is primarily to be clear about the distinction, but we would only use it in modeling data if absolutely needed. For example, we would define an 'HLA gene block' as a subclass of 'genomic feature', and assert that HLA-A, HLA-B, and HLA-C genes are part/subsequences of this HLA gene block (as opposed to modeling this as an 'HLA locus' and asserting that the HLA-A, HLA-B, and HLA-C genes occupy this locus).
1. A genomic location (aka locus) is defined by its begin and end coordinates on a reference genome, independent of a particular sequence that may reside there. In GENO, we say that a genomic location is occupied_by a 'sequence feature' - where the identity of this feature depends on both it sequence, and its location in the genome (i.e. the locus it occupies). For example, the 'ATG' sequence beginning the ORF of the human SHH gene shares the *same sequence* as the 'ATG' beginning the ORF of the human AKT gene. But these are *distinct sequence features* because they occupy different genomic locations. 2. A given genomic location (e.g. the human SHH gene locus) may be occupied by different alleles (e.g. different alleles of the SHH gene). Within the genome of a single diploid organism, there is potential for two alleles to exist at such a locus (i.e. two different versions of the SHH gene). And across genomes of all members of a species, many more alleles of the SHH gene may exist and occupy this same locus. 3. The notion of a genomic location in the realm of biological sequences is analogous to a BFO:spatiotemporal region in the realm of physical entities. A spatiotemporal region can be occupied_by physical objects, while a genomic location is occupied_by sequence features. Just as a spatiotemporal region is distinct from an object that occupies it, so too a genomic locus is distinct from a sequence feature that occupies it. As a more concrete example, consider the distinction between a street address and the building that occupies it as analogous to the relationship between a genomic location and the feature that resides there.
genomic feature location
A material entity that is an organism, derived from an organism, or composed of organisms (e.g. a cell line, biosample, tissue culture, population, etc).
useful organizational term to collect entities that have genomes/genotypes.
organismal entity
A sequence feature whose identity is additionally dependent on the context or state of the material sequence molecule in which the feature is concretized. This context/state describes factors external to the feature's intrinsic sequence and position that can influences its expression, such as being targeted by gene-knockdown reagents, or an epigenetic modification.
GENO defines three levels of sequence-related artifacts, which are distinguished by their identity criteria. 1. 'Biological sequence' identity is dependent only on the ordering of units that comprise the sequence. 2. 'Sequence feature' identity is dependent on its sequence and the genomic location of the sequence (this is consistent with the definition of 'sequence feature' in the Sequence Ontology). 3. 'Qualified sequence feature' identity is additionally dependent on some aspect of the physical state or context of the genetic material in which the feature is concretized. This third criteria is extrinsic to its sequence and its genomic location. For example, the feature's physical concretization being targeted by a gene knockdown reagent in a cell (e.g. the zebrafish Shha gene as targeted by the morpholino 'Shha-MO1'), or its being transiently expressed from a recombinant expression construct (e.g. the human SHH gene as expressed in a mouse Shh knock-out cell line), or its having been epigenetically modified in a way that alters its expression level or pattern (e.g. the human SHH gene with a specific methylation pattern).
Modeling sequence entities at this 'qualified' level is useful for distinguishing cases where features with identical sequence and position as separate instances - based on their material bearers being found in different contexts. For example, consider a situation where the zebrafish shha gene (a sequence feature) is targeted in two experimental groups of fish by two different morpholinos, and phenotypes are assessed for each. We want to be able to represent two 'variants' of the shha gene in this scenario as separate 'qualified sequence feature' instances so we can capture data about the phenotypes resulting from each - just as we would separately represent to different sequence variants (alleles) of the shha gene at the sequence feature level so that we can track their associated phenotypes.
qualified sequence feature
'Sets' are used to represent entities that are typically collections of more than one member. But we allow for sets that contain 0 members (an 'empty' set) or 1 member (a 'singleton' or 'unit' set), consistent with the concept of 'matehmatical sets'.
qualified sequence feature set
A biolocical sequence, or set of such sequences.
biological sequence or set
A biological sequence that is of genomic origin (i.e. carries sequence from the genome of a cell or organism).
A sequence being 'of genomic origin' here means only that it has been located to the genome of some organism by alignment with some reference genomic sequence. This is because the sequence was originally identified in, or artificially created to replicate, sequence from an organism's genome.
genomic sequence
A molecular process that can be carried out by the action of a single macromolecular machine, usually via direct physical interactions with other molecular entities. Function in this sense denotes an action, or activity, that a gene product (or a complex) performs.
This is the same as GO molecular function
gene product or complex activity
A biological process is the execution of a genetically-encoded biological module or program. It consists of all the steps required to achieve the specific biological objective of the module. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence.
A biological process represents a specific objective that the organism is genetically programmed to achieve. Biological processes are often described by their outcome or ending state, e.g., the biological process of cell division results in the creation of two daughter cells (a divided cell) from a single parent cell. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence.
biological process
Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule.
A biological process whose specific outcome is the progression of an integrated living unit: an anatomical structure (which may be a subcellular structure, cell, tissue, or organ), or organism over time from an initial condition to a later condition. [database_cross_reference: GOC:isa_complete]

objective specification
In the protocol of a ChIP assay the objective specification says to identify protein and DNA interaction.
A directive information entity that describes an intended process endpoint. When part of a plan specification the concretization is realized in a planned process in which the bearer tries to effect the world so that the process endpoint is achieved.
2009-03-16: original definition when imported from OBI read: "objective is an non realizable information entity which can serve as that proper part of a plan towards which the realization of the plan is directed."
2014-03-31: In the example of usage ("In the protocol of a ChIP assay the objective specification says to identify protein and DNA interaction") there is a protocol which is the ChIP assay protocol. In addition to being concretized on paper, the protocol can be concretized as a realizable entity, such as a plan that inheres in a person. The objective specification is the part that says that some protein and DNA interactions are identified. This is a specification of a process endpoint: the boundary in the process before which they are not identified and after which they are. During the realization of the plan, the goal is to get to the point of having the interactions, and participants in the realization of the plan try to do that.

information carrier
In the case of a printed paperback novel the physicality of the ink and of the paper form part of the information bearer. The qualities of appearing black and having a certain pattern for the ink and appearing white for the paper form part of the information carrier in this case.
A quality of an information bearer that imparts the information content
12/15/09: There is a concern that some ways that carry information may be processes rather than qualities, such as in a 'delayed wave carrier'.
2014-03-10: We are not certain that all information carriers are qualities. There was a discussion of dropping it.
data item
Data items include counts of things, analyte concentrations, and statistical summaries.
An information content entity that is intended to be a truthful statement about something (modulo, e.g., measurement precision or other systematic errors) and is constructed/acquired by a method which reliably tends to produce (approximately) truthful statements.
2/2/2009 Alan and Bjoern discussing FACS run output data. This is a data item because it is about the cell population. Each element records an event and is typically further composed a set of measurment data items that record the fluorescent intensity stimulated by one of the lasers.
2009-03-16: data item deliberatly ambiguous: we merged data set and datum to be one entity, not knowing how to define singular versus plural. So data item is more general than datum.
2009-03-16: removed datum as alternative term as datum specifically refers to singular form, and is thus not an exact synonym.

An information content entity is a non-realizable information entity that 'is encoded in' some digital or physical entity.
An information content entity whose concretizations indicate to their bearer how to realize them in a process.
2009-03-16: provenance: a term realizable information entity was proposed for OBI (OBI_0000337) , edited by the PlanAndPlannedProcess branch. Original definition was "is the specification of a process that can be concretized and realized by an actor" with alternative term "instruction".It has been subsequently moved to IAO where the objective for which the original term was defined was satisfied with the definitionof this, different, term.
2013-05-30 Alan Ruttenberg: What differentiates a directive information entity from an information concretization is that it can have concretizations that are either qualities or realizable entities. The concretizations that are realizable entities are created when an individual chooses to take up the direction, i.e. has the intention to (try to) realize it.
8/6/2009 Alan Ruttenberg: Changed label from "information entity about a realizable" after discussions at ICBO
Werner pushed back on calling it realizable information entity as it isn't realizable. However this name isn't right either. An example would be a recipe. The realizable entity would be a plan, but the information entity isn't about the plan, it, once concretized, *is* the plan. -Alan

'Plan' includes a future direction sense. That can be problematic if plans are changed during their execution. There are however implicit contingencies for protocols that an agent has in his mind that can be considered part of the plan, even if the agent didn't have them in mind before. Therefore, a planned process can diverge from what the agent would have said the plan was before executing it, by adjusting to problems encountered during execution (e.g. choosing another reagent with equivalent properties, if the originally planned one has run out.)
Stub class to serve as root of hierarchy for experimental techniques and processes, defined in GENO or imported from ontologies such as OBI and ERO.
We are only considering successfully completed planned processes. A plan may be modified, and details added during execution. For a given planned process, the associated realized plan specification is the one encompassing all changes made during execution. This means that all processes in which an agent acts towards achieving some objectives is a planned process.

Here is the entire email summary, on which the definition is based: 1) there are organization_member_roles (president, treasurer, branch editor), with individual persons as bearers 2) there are organization_roles (employer, owner, vendor, patent holder) 3) an organization has a charter / rules / bylaws, which specify what roles there are, how they should be realized, and how to modify the charter/rules/bylaws themselves. It is debatable what the organization itself is (some kind of dependent continuant or an aggregate of people). This also determines who/what the bearer of organization_roles' are. My personal favorite is still to define organization as a kind of 'legal entity', but thinking it through leads to all kinds of questions that are clearly outside the scope of OBI. Interestingly enough, it does not seem to matter much where we place organization itself, as long as we can subclass it (University, Corporation, Government Agency, Hospital), instantiate it (Affymetrix, NCBI, NIH, ISO, W3C, University of Oklahoma), and have it play roles. This leads to my proposal: We define organization through the statements 1 - 3 above, but without an 'is a' statement for now. We can leave it in its current place in the is_a hierarchy (material entity) or move it up to 'continuant'. We leave further clarifications to BFO, and close this issue for now.

An information content entity that specifies a value within a classification scheme or on a quantitative scale.
This term is currently a descendant of 'information content entity', which requires that it 'is about' something. A value specification of '20g' for a measurement data item of the mass of a particular mouse 'is about' the mass of that mouse. However there are cases where a value specification is not clearly about any particular. In the future we may change 'value specification' to remove the 'is about' requirement.

k-means clustering
A k-means clustering is a data transformation which achieves a class discovery or partitioning objective, which takes as input a collection of objects (represented as points in multidimensional space) and which partitions them into a specified number k of clusters. The algorithm attempts to find the centers of natural clusters in the data. The most common form of the algorithm starts by partitioning the input points into k initial sets, either at random or using some heuristic data. It then calculates the mean point, or centroid, of each set. It constructs a new partition by associating each point with the closest centroid. Then the centroids are recalculated for the new clusters, and the algorithm repeated by alternate applications of these two steps until convergence, which is obtained when the points no longer switch clusters (or alternatively centroids are no longer changed).
WEB: http://en.wikipedia.org/wiki/K-means
hierarchical clustering
A hierarchical clustering is a data transformation which achieves a class discovery objective, which takes as input data item and builds a hierarchy of clusters. The traditional representation of this hierarchy is a tree (visualized by a dendrogram), with the individual input objects at one end (leaves) and a single cluster containing every object at the other (root).

chromosome arm
Any extent of continuous biological sequence.
A sequence feature is an extent of 'located' biological sequence, whose identity is determined by both its inherent sequence (ordering of monomeric units) and its position (start and end coordinates based on alignment with some reference). By contrast, 'biological sequences' are identified and distinguished only by their inehrent sequence, and not their position. Accordingly, the 'ATG' start codon in the coding DNA sequence of the human AKT gene is the same 'sequence' as the 'ATG' start codon in the human SHH gene, but these represent two distinct 'sequence features' in virtue of their different positions in the genome.

junction
A region (or regions) that includes all of the sequence elements necessary to encode a functional transcript. A gene may include regulatory regions, transcribed regions and/or other functional sequence regions.
Regarding the distinction between a 'gene' and a 'gene allele': Every zebrafish genome contains a 'gene allele' for every zebrafish gene. Many will be 'wild-type' or at least functional gene alleles. But some may be alleles that are mutated or truncated so as to lack functionality. According to current SO criteria defining genes, a 'gene' no longer exists in the case of a non-functional or deleted variant. But the 'gene allele' does exist - and its extent is that of the remaining/altered sequence based on alignment with a reference gene. Even for completely deleted genes, an allele of the gene exists (and here is equivalent to the junction corresponding to the where gene would live based on a reference alignment).
A gene is any 'gene allele' that produces a functional transcript (ie one capable of translation into a protein, or independent functioning as an RNA), when encoded in the genome of some cell or virion.
A quantitative trait locus (QTL) is a polymorphic locus which contains alleles that differentially affect the expression of a continuously distributed phenotypic trait.

An attribute to describe a region that was modified in vitro.
engineered_region
An extended region of sequence corresponding to a defined feature that is a proper part of a chromosome, e.g. a chromosomal 'arm', 'region', or 'band'.
A gene that has been transferred naturally or by any of a number of genetic engineering techniques into a cell or organism where it is foreign (i.e. does not belong to the host genome).
On the relationship between 'transgenic insertions', 'transgenes', and 'alleles' Transgenic insertions are sequence alterations comprised of foreign/exogenous sequence. This sequence can be from the same or different species as the host cell or genome - it is exogenous in virtue of it being additional sequence inserted into the original host genome. A given transgenic insertion may create one or more transgenes when introduced into a host genome. The extent of a transgene is spans all features needed to drive its expression in the host genome. In most cases a transgenic insertion completely contains one or more transgenes that are fully competent to drive expression in the host genome. But in some cases, a transgenic insertion may carry only part of the final transgene it creates - which requires additional endogenous sequences in the vicinity of its insertion site to complete a functional gene (e.g. this is the case for enhancer traps or gene traps) to complete. In addition to the transgenes they create upon genomic integration, transgenic insertions can create variant alleles by disrupting a known endogenous gene/locus. Variant alleles are versions of a particular genomic features (typically genes), that are altered in their sequence relative to some reference. An insertion that disrupts an endogenous gene would be considered a 'sequence alteration' (sensu SO) which creates a 'variant gene allele'. From the perspective of this disrupted gene, the origin or transgenic nature of this insertion is irrelevant - what matters here is that the gene's sequence has been altered to create an allele. For the purposes of modeling, any transgene(s) created when an endogenous gene is interrupted by an insertion is considered/modeled separately from the allele of the endogenous gene that is created by the insertion. The transgenic insertion, which is simply a sequence alteration in the host genome, is then linked to any transgenes that it contributes to or overlaps with or contains. The model of the Flybase example HERE illustrates this approach.
Transgenes can exist as integrated into the host genome, or extra-chromosomally on replicons or transiently carried/expressed vectors. What matters is that they are active in the context of a foreign biological system (typically a cell or organism). Note that transgenes as defined here are not necessarily from a different taxon than that of the host genome. For example, a Mus musculus gene over-expressed from a chromosomally-integrated expression construct in a Mus musculus genome qualifies as a transgene because it is exogenous to the host genome.
transgene
A multiple nucleotide polymorphism with alleles of common length > 1, for example AAA/TTT.
A variation that increases or decreases the copy number of a given region.
A collection of sequence features (typically a collection of chromosomes) that covers the sum genetic material within a cell or virion (where 'genetic material' refers to any nucleic acid that is part of a cell or virion and has been inherited from an ancestor cell or virion, and/or can be replicated and inherited by its progeny)
Genotype vs Genome in GENO: An (genomic) genotype is an information artifact representing a shorthand syntax for specifying what is known about variation in a genome sequence. This syntax has reference and variant components - a 'reference genome' and 'genomic variation complement' - that must be operated on to resolve a final genome sequence (i.e. substituting all sequences specified by the 'genomic variation complement' for the corresponding sequences in the 'reference genome'). So, while the total sequence content represented in a genotype may be greater than that in a genome, the intended resolution of these sequences is to arrive at a single genome sequence.
A genome is considered the complement of all heritable sequence features in a given cell or organism (chromosomal or extrachromosomal). This is typically a collection of >1 sequence molecules (e.g. chromosomes), but in some organisms (e.g. bacteria) it may be a single sequence macromolecule (e.g. a circular plasmid). For this reason 'genome' classifies under 'sequence feature complement'.
A few examples highlighting the distinction of 'sequence alterations' from their parent 'variant allele': 1. Consider NM_000059.3(BRCA2):c.631G>A variation in the BRCA2 gene. This mutation of a single nucleotide creates a gene allele whose extent is that of the entire BRCA2 gene. This version of the full BRCA2 gene is a 'variant allele', while the extent of sequence spanning just the single altered base is a 'sequence alteration'. See https://www.ncbi.nlm.nih.gov/snp/80358871. 2. Consider the NM_000059.3(BRCA2):c.132_133ins8 variation in the BRCA2 gene. This 8 bp insertion creates a gene allele whose extent is that of the entire BRCA2 gene. This version of the full BRCA2 gene is a 'variant allele', while the extent of sequence spanning just the 8 bp insertion is a 'sequence alteration'. See https://www.ncbi.nlm.nih.gov/snp/483353112. 3. Consider the NM_000059.3(BRCA2):c.22_23delAG variation in the BRCA2 gene. This 2 bp deletion creates a gene allele whose extent is that of the entire BRCA2 gene. This version of the full BRCA2 gene is a 'variant allele', while the junction where the deletion occured is a 'sequence alteration' with an extent of zero. See https://www.ncbi.nlm.nih.gov/snp/483353112.
A sequence_alteration is a sequence_feature whose extent is the deviation from another sequence.
1. A 'sequence alteration' is an allele whose sequence deviates in its entirety from that of other features found at the same genomic location (i.e. it deviates along its entire extent). In this sense, 'sequence alterations' represent the minimal extent an allele can take - i.e. that which is variable with some other feature along its entire sequence). An example is a SNP or insertion. Alleles whose extent goes beyond the specific sequence that is known to be variable are not sequence alterations. These are alleles that represent alternate versions of some larger, named feature. The classic example here is a 'gene allele', which spans the extent of an entire gene, and contains one or more sequence alterations (regions known to vary) as part. 2. Sequence alterations are not necessarily 'variant' in the sense defined in GENO (i.e. being 'variant with' some reference sequence). In any comparison of alleles at a particular location, the choice of a 'reference' is context-dependent - as comparisons in other contexts might consider a different allele to be the reference. So while sequence alterations are usually considered 'variant' in the context in which they are considered, this variant status may not hold at all times. For this reason, the 'sequence alteration' class is not made an rdfs:subClassOf 'variant allele'. For a particular instance of a sequence alteration, howver, we may in some cases be able to rdf:type it as a 'varaint allele' and a 'sequence alteration', in situations where we can be confident that the feature will *never* be considered a reference. For example, experimentally generated mutations in model organism genes that are created expressly to vary from an established reference. 3. Note that we consider novel features gained in a genome to be sequence alterations, including aneusomic chromosomes gained through a non-disjunction event during replication, or extrachromosomal replicons that become part of the heritable genome of a cell or organism.

exploratory term
exemplar term
example to be eventually removed
failed exploratory term
The term was used in an attempt to structure part of the ontology but in retrospect failed to do a good job
metadata complete
Class has all its metadata, but is either not guaranteed to be in its final location in the asserted IS_A hierarchy or refers to another class that is not complete.
organizational term
Term created to ease viewing/sort terms for development purpose, and will not be included in a release
The term was created to ease viewing/sorting terms for development purposes, but will not be included in a release.
ready for release
Class has undergone final review, is ready for use, and will be included in the next release. Any class lacking "ready_for_release" should be considered likely to change place in hierarchy, have its definition refined, or be obsoleted in the next release. Those classes deemed "ready_for_release" will also derived from a chain of ancestor classes that are also "ready_for_release."
metadata incomplete
Class is being worked on; however, the metadata (including definition) are not complete or sufficiently clear to the branch editors.
uncurated
Nothing done yet beyond assigning a unique class ID and proposing a preferred term.
pending final vetting
All definitions, placement in the asserted IS_A hierarchy and required minimal metadata are complete. The class is awaiting a final review by someone other than the term editor.
placeholder removed
terms merged
An editor note should explain what were the merged terms and the reason for the merge.
term imported
This is to be used when the original term has been replaced by a term imported from an other ontology. An editor note should indicate what is the URI of the new term to use.
term split
This is to be used when a term has been split in two or more new terms. An editor note should indicate the reason for the split and indicate the URIs of the new terms created.
universal
Hard to give a definition for. Intuitively a "natural kind" rather than a collection of any old things, which a class is able to be, formally. At the meta level, universals are defined as positives, are disjoint with their siblings, have single asserted parents.
A Formal Theory of Substances, Qualities, and Universals, http://ontology.buffalo.edu/bfo/SQU.pdf
defined class
A defined class is a class that is defined by a set of logically necessary and sufficient conditions but is not a universal
"definitions", in some readings, always are given by necessary and sufficient conditions. So one must be careful (and this is difficult sometimes) to distinguish between defined classes and universal.
named class expression
A named class expression is a logical expression that is given a name. The name can be used in place of the expression.
named class expressions are used in order to have more concise logical definition but their extensions may not be interesting classes on their own. In languages such as OWL, with no provisions for macros, these show up as actuall classes. Tools may with to not show them as such, and to replace uses of the macros with their expansions
to be replaced with external ontology term
Terms with this status should eventually replaced with a term from another ontology.
requires discussion
A term that is metadata complete, has been reviewed, and problems have been identified that require discussion before release. Such a term requires editor note(s) to identify the outstanding issues.
