Attributes

Own

  • object 1..1
    • Description: connects an association to the object of the association. For example, in a gene-to-phenotype association, the gene is subject and phenotype is object.
    • Range: NamedThing

Inherited from association:

  • subject 1..1
    • Description: connects an association to the subject of the association. For example, in a gene-to-phenotype association, the gene is subject and phenotype is object.
    • Range: NamedThing
  • predicate 1..1
    • Description: A high-level grouping for the relationship type. AKA minimal predicate. This is analogous to category for nodes.
    • Range: PredicateType
  • object 1..1
    • Description: connects an association to the object of the association. For example, in a gene-to-phenotype association, the gene is subject and phenotype is object.
    • Range: NamedThing
  • negated 0..1
    • Description: if set to true, then the association is negated i.e. is not true
    • Range: Boolean
  • qualifiers 0..*

    • Range: OntologyClass
  • publications 0..*

    • Range: EvidenceType
  • knowledge source 0..1
    • Description: An Information Resource from which the knowledge expressed in an Association was retrieved, directly or indirectly. This can be any resource through which the knowledge passed on its way to its currently serialized form. In practice, implementers should use one of the more specific subtypes of this generic property.
    • Range: String
  • primary knowledge source 0..1
    • Description: The most upstream source of the knowledge expressed in an Association that an implementer can identify. Performing a rigorous analysis of upstream data providers is expected; every effort is made to catalog the most upstream source of data in this property. Only one data source should be declared primary in any association. “aggregator knowledge source” can be used to capture non-primary sources.

Note: typically the “subclass of” and “part of” relations are used to construct the closure, but other relations may be used as well.
  • object category closure 0..*

  • type 0..*
  • category 0..*
    • Description: Name of the high level ontology class in which this entity is categorized. Corresponds to the label for the biolink entity type class.
  • In a neo4j database this MAY correspond to the neo4j label tag.
  • In an RDF database it should be a biolink model class URI. This field is multi-valued. It should include values for ancestors of the biolink class; for example, a protein such as Shh would have category values biolink:Protein, biolink:GeneProduct, biolink:MolecularEntity, … In an RDF database, nodes will typically have an rdf:type triples. This can be to the most specific biolink class, or potentially to a class more specific than something in biolink. For example, a sequence feature f may have a rdf:type assertion to a SO class such as TF_binding_site, which is more specific than anything in biolink. Here we would have categories {biolink:GenomicEntity, biolink:MolecularEntity, biolink:NamedThing}
