The Open Geospatial Consortium (OGC) Membership seeks public comment on a new version of the OGC Catalogue Service interface standard. This standard specifies a design pattern for defining interfaces to publish and search collections of descriptive information (metadata) about geospatial data, services and related information objects.

There are three documents being considered. The first document defines the General Model for a catalogue service. The General Model is technology neutral. Therefore, the second document describes the rules for deploying a Catalogue Service in the HTTP environment, also known as Catalogue Service for the Web, or CS-W. The third document contains a detailed Abstract Test Suite for conformance classes described in the CS-W document. The main changes from version 2.0.2 include the migration to a fully stateless model, removal/deprecation of the Z39.50 and CORBA bindings, inclusion of OpenSearch compatibility, and support for the OGC modular specification approach for specifying requirements and conformance classes.

The new version of the candidate OGC Catalogue Service interface standard is available for comment at http://www.opengeospatial.org/standards/requests/121.
