Attributes

Own

• abstract _OPT
  • Description: an abstract class is a high level class or slot that is typically used to group common slots together and cannot be directly instantiated.
  • range: Boolean
• apply_to _0..*
  • Description: Used to extend class or slot definitions. For example, if we have a core schema where a gene has two slots for identifier and symbol, and we have a specialized schema for my_organism where we wish to add a slot systematic_name, we can avoid subclassing by defining a class gene_my_organism, adding the slot to this class, and then adding an apply_to pointing to the gene class. The new slot will be ‘injected into’ the gene class.
  • range: Definition
• created_by _OPT
  • Description: agent that created the element
  • range: Uriorcurie
• created_on _OPT
  • Description: time at which the element was created
  • range: Datetime
• is_a _OPT
  • Description: specifies single-inheritance between classes or slots. While multiple inheritance is not allowed, mixins can be provided effectively providing the same thing. The semantics are the same when translated to formalisms that allow MI (e.g. RDFS/OWL). When translating to a SI framework (e.g. java classes, python classes) then is a is used. When translating a framework without polymorphism (e.g. json-schema, solr document schema) then is a and mixins are recursively unfolded
  • range: Definition
• last_updated_on _OPT
  • Description: time at which the element was last updated
  • range: Datetime
• mixin _OPT
  • Description: this slot or class can only be used as a mixin – equivalent to abstract
  • range: Boolean
• mixins _0..*
  • Description: List of definitions to be mixed in. Targets may be any definition of the same type
  • range: Definition
• modified_by _OPT
  • Description: agent that modified the element
  • range: Uriorcurie
• status _OPT
  • Description: status of the element
  • range: Uriorcurie
  • Example: bibo:draft None
• values_from _0..*
  • Description: the identifier of a “value set” – a set of identifiers that form the possible values for the range of a slot
  • range: Uriorcurie

Inherited from element:

  • Description: the identifier of this class or slot must begin with one of the URIs referenced by this prefix
  • range: Ncname
• imported_from _OPT
  • Description: the imports entry that this element was derived from. Empty means primary source
  • range: String
• in_subset _0..*
  • Description: used to indicate membership of a term in a defined subset of biolink terms used for a particular domain or application (e.g. the translator_minimal subset holding the minimal set of predicates used in a translator knowledge graph)
  • range: SubsetDefinition
• local_names _0..*
  • range: LocalName
• mappings _0..*
  • Description: A list of terms from different schemas or terminology systems that have comparable meaning. These may include terms that are precisely equivalent, broader or narrower in meaning, or otherwise semantically related but not equivalent from a strict ontological perspective.
