• id - A unique identifier for an entity. Must be either a CURIE shorthand for a URI or a complete URI
• iri - An IRI for an entity. This is determined by the id using expansion rules.
• name - A human-readable name for an attribute or entity.
• relation
• source - a lightweight analog to the association class ‘has provider’ slot, which is the string name, or the authoritative (i.e. database) namespace, designating the origin of the entity to which the slot belongs.
• type
  • category - Name of the high level ontology class in which this entity is categorized. Corresponds to the label for the biolink entity type class.

Defined

• BiologicalSequence (String)
• Boolean (Bool) - A binary (true or false) value
• CategoryType (Uriorcurie) - A primitive type in which the value denotes a class within the biolink model. The value must be a URI or a CURIE. In a Neo4j representation, the value should be the CURIE for the biolink class, for example biolink:Gene. For an RDF representation, the value should be a URI such as https://w3id.org/biolink/vocab/Gene
• ChemicalFormulaValue (str) - A chemical formula
• Date (XSDDate) - a date (year, month and day) in an idealized calendar
• Datetime (XSDDateTime) - The combination of a date and time
• Decimal (Decimal) - A real number with arbitrary precision that conforms to the xsd:decimal specification
• Double (float) - A real number that conforms to the xsd:double specification
• Float (float) - A real number that conforms to the xsd:float specification
• FrequencyValue (String)
• Integer (int) - An integer
• IriType (Uriorcurie) - An IRI
• LabelType (String) - A string that provides a human-readable name for an entity
• NarrativeText (String) - A string that provides a human-readable description of something
• Ncname (NCName) - Prefix part of CURIE
• Nodeidentifier (NodeIdentifier) - A URI, CURIE or BNODE that represents a node in a model.
• Objectidentifier (ElementIdentifier) - A URI or CURIE that represents an object in the model.
• PercentageFrequencyValue (Double)
• PredicateType (Uriorcurie) - A CURIE from the biolink related_to hierarchy. For example, biolink:related_to, biolink:causes, biolink:treats.
• Quotient (Double)
• String (str) - A character string
• SymbolType (String)
• Time (XSDTime) - A time object represents a (local) time of day, independent of any particular day
• TimeType (Time)
• Unit (String)
• Uri (URI) - a complete URI
• Uriorcurie (URIorCURIE) - a URI or a CURIE
