The Open Geospatial Consortium (OGC®) announces the release of version 3.0 of the OGC Catalogue Services standard. Catalogue services support the ability to publish and search geospatial data and services. Information (metadata) provided by catalogues supports evaluation and further processing by both humans and software. The OGC Catalogue interface standards specify the interfaces, bindings, and a framework for defining application profiles required to discover and access digital catalogues of metadata for geospatial data, services, and related resource information. The query capabilities of the OGC General Catalogue Model provide a minimum set of data types and query operations that can be assumed of OGC Compliant Catalogue implementations. In addition, these query capabilities provide a high degree of flexibility enabling alternate styles of query, result presentation, and the potential support of any geo-enabled query language.
