Class RDFTermFactory

A factory object for the creation of RDF Terms.

The main reason for using this factory is that fact that some terms may be used before they are formally defined. The factory will create a term with the minimal information needed, and then promote it to a class, property, etc., when defined.

Also: some terms refer to internal terms, i.e., defined by the input yml file, and some refer to external terms, i.e., defined by external ontologies. The factory will put in the correct properties, used by the generator functions to HTML, Turtle, or JSON-LD.

Terms are stored in an internal map, indexed by their curie. The curie is used even if the term is defined locally; the general prefix of the vocabulary (defined in the yml file) is used for that purpose.

Note that the factory includes some methods that are not (yet?) used in the package. They are included for possible future use.

get

has

  • has(index: string): boolean

  • Check whether a term with a curie has been defined.

    Parameters

    • index: string

    Returns boolean

individual

initialize

listPrefixes

  • listPrefixes(): string[]

  • List the prefixes used by the vocabulary

    Returns string[]

promoteToClass

  • promoteToClass(term: RDFTerm): RDFClass

  • Promote an unknown term to a class. This is necessary when a term is used, e.g., in a range or domain, before it is defined.

    (Currently unused in the package.)

    Parameters

    Returns RDFClass

promoteToDatatype

  • promoteToDatatype(term: RDFTerm): RDFDatatype

  • Promote an unknown term to a datatype. This is necessary when a term is used, e.g., in a range or domain, before it is defined.

    (Currently unused in the package.)

    Parameters

    Returns RDFDatatype

property

term

  • term(index: string): RDFTerm

  • Create or retrieve an term. When created, the term is initially considered as an unknown term.

    Parameters

    • index: string

    Returns RDFTerm

usesPrefix

  • usesPrefix(prefix: string): boolean

  • Does the system really use a predefined prefix?

    Parameters

    • prefix: string

    Returns boolean

Staticequals

StaticincludesCurie

  • includesCurie(terms: RDFTerm[], index: string): boolean

  • Does a curie identify a term in a list of terms.

    Parameters

    Returns boolean

StaticincludesTerm

StaticisClass

StaticisDatatype

StaticisIndividual

StaticisProperty

StaticisUnknown
