Welcome to the OGC Definitions Server
The OGC publishes definitions using the SKOS vocabulary (or "taxonomy") model in both human- and machine-readable forms.
Some definitions have richer information models with alternative profiles of the content available.
Vocabularies are managed in sets called "ConceptSchemes", and definitions can usually be accessed individually as "Concepts" or as a set.
The "alternate profiles" will provide a complete list of the available resources per definition.
See the Definitions Server About Page for more information about the OGC Definitions Server.
