OGC approves important spatial catalog specification

The Open GIS Consortium has announced industry approval of an expanded version of the OpenGIS Catalog Service Implementation Specification. The OpenGIS Catalog Service Specification version 1.1.1 documents industry consensus regarding an open, standard interface to online catalogs for geographic information and web-accessible geoprocessing services. Industry agreement on a common interface for publishing metadata and supporting discovery of geospatial data and services is an important step toward giving Web users and applications access to all types of “where” information.

Doug Nebert of the US Federal Geographic Data Committee, who chairs the OGC Technical Committee Catalog Working Group, said, “In government, business and academia, technical and semantic non-interoperability have long frustrated discovery and sharing of digital geographic information. This specification is the world’s industry-approved design for a key part of all future internet-based solutions to these problems.”

Version 1.1.1 is more comprehensive than earlier OpenGIS Catalog Service Specification versions and proposals. It addresses the controlled enterprise environment where a-priori knowledge exists about the client and server, and it also addresses the global Internet case where no a-priori knowledge exists between client and server. It is consistent with existing and pending geomatics and metadata standards under the ISO Technical Committee 211, and it is consistent with XML data discovery and processing and with the emerging Web Services infrastructure.
