Semantic Resources

The types of Semantic Web resources published here are:

  • SKOS data model vocabulary versions of 19* series standards' codelists

  • OWL ontology versions of 19* series standards' data models

Currently, as of May 2025, the only Semantic Web resources published by TC-211 are some of the codelist vocabularies which are hosted for the TC-211 by the Open Geospatial Consortium (OGC) on their reference data platform known as the 'OGC Rainbow'.

See the entire catalogue of TC-211 resources at:

In July 2025, TC-211 plans to start testing the online delivery of ontologies.

See the section Published so far below for the complete list of published resources.

Persistent Identifiers

TC-211 Semantic Web resources all have persistent identifiers assigned to them in the form of IRIs - web page URL addresses.

You can go to the human-readable form of any TC-211 Semantic Web resource by just clicking on its IRI, for example, here is the IRI for ISO19115’s Role Code codelist:

Maintenance

This web page and the TC’s Semantic Web resources are managed by the TC’s Advisory Group 6: Group on Ontology Maintenance (GOM) and the OGC.
