CGI's Vocabularies System

Welcome to the Commission for the Management and Application of Geosceicne Information (CGI)'s public vocabulary system. This tool is an instance of VocPrez, a read-only web delivery system for Simple Knowledge Organization System (SKOS)-formulated RDF vocabularies.


This system publishes vocabularies from two sources: GeoSciML & EarthResourceML.

Vocabulary sources:

Vocabulary Modelling

CGI conceives of vocabularies as being synonymous with SKOS' skos:ConceptScheme class, so each GA vocab is an instance of skos:ConceptScheme. Not all users of SKOS make this conception.



All the content of all vocabs can be accessed individually in web page (HTML) and machine-readable forms. Each list fo vocabs, vocabulary and Concept web page contains a link to the listing of all profiles and formats available for that object. Look for the Alternate Profiles hyperlink.


All of the vocabularies in this system are accessible via a single SPARQL endpoint:
