]> Identifiers and Indices Ontology This ontology defines abstract concepts for representation of identifiers, identification schemes, indices and indexing schemes for use in other FIBO ontology elements. https://opensource.org/licenses/MIT The https://spec.edmcouncil.org/fibo/ontology/FND/20140801/Arrangements/IdentifiersAndIndices.rdf version of this ontology was introduced as a part of the issue resolutions identified in the FIBO FND 1.0 FTF report and in https://spec.edmcouncil.org/fibo/ontology/FND/1.0/AboutFND-1.0/. It was further revised in the FTF in advance of the Long Beach meeting to promote Collection to the top level in the hierarchy, resulting in https://spec.edmcouncil.org/fibo/ontology/FND/20141101/Arrangements/Arrangements/. The https://spec.edmcouncil.org/fibo/ontology/FND/20141101/Arrangements/IdentifiersAndIndices.rdf version of this ontology was revised for the FIBO 2.0 RFC to incorporate mappings to LCC. The https://spec.edmcouncil.org/fibo/ontology/FND/20180801/Arrangements/IdentifiersAndIndices.rdf version of this ontology was revised to replace hasDefinition with isDefinedIn to clarify intent. The https://spec.edmcouncil.org/fibo/ontology/FND/20190701/Arrangements/IdentifiersAndIndices.rdf version of this ontology was revised to eliminate duplication of concepts with LCC. The https://spec.edmcouncil.org/fibo/ontology/FND/20200201/Arrangements/IdentifiersAndIndices.rdf version of this ontology was revised to add the concept of a time-constrained, reassignable identifier as well as the concept of a composite identifier. The https://spec.edmcouncil.org/fibo/ontology/FND/20211101/Arrangements/IdentifiersAndIndices.rdf version of this ontology was revised loosen a constraint on composite identifier and add regular expression annotations to support ordered constituents. The https://spec.edmcouncil.org/fibo/ontology/FND/20220401/Arrangements/IdentifiersAndIndices.rdf version of the ontology was modified to use the Commons Ontology Library (Commons) Annotation Vocabulary rather than the OMG's Specification Metadata vocabulary. The https://spec.edmcouncil.org/fibo/ontology/FND/20230101/Arrangements/IdentifiersAndIndices.rdf version of this ontology was modified to use the Commons Ontology Library (Commons) rather than the OMG's Languages, Countries and Codes (LCC), eliminating redundancies in FIBO as appropriate.

If there is no initial assignment date, then the identifier is assumed to be assigned up until the termination date, if any. construct regex indicates how to compose the supplied character string from its components has assignment termination date the date on which an identifier is released from its assignment to some resource has initial assignment date the date on which an identifier is first assigned to some resource is index to that to which the index refers parse regex indicates how to deconstruct the supplied character string into its components For a fictional business identifier, the rule used to parse a composite identifier might be fibo-fnd-arr-id:parseRegex "RA([0-9]{6})-([0-9A-Z]*)", and fibo-fnd-arr-id:constructRegex "$1-$2", where RA represents a text value corresponding to the registration authority for the business identifier. Use parseRegex and constructRegex annotation properties to express the rules for deconstructing and composing the actual composite identifiers from their constituent parts as appropriate.
