CONCEPTSCHEMES

An aggregation of one or more Concepts defined as a “controlled vocabulary” or “thesaurus” or other classification scheme identifying the namespace and authoritative source of the Concepts and their definitions. Rationale: Used to organize information at the conceptual level in a domain-specific vocabulary, enabling semantic inferencing and classification of information that helps the end-user to find relevant information (e.g., restrict searches for resources by Concepts of a particular ConceptScheme). Essential when more than one domain vocabulary is being used to categorize resources. Refer to the GeoPlatform Portfolio Model for further information.
