March 20, 2014 - The Geospatial Platform team is pleased to announce the availability of an open standards compliant catalog service API supporting Geoplatform.gov and Data.gov. Supporting the Open Geospatial Consortium (OGC) Catalog Service for the Web (CSW) it provides an interface for query and presentation of results regarding data, services, and applications registered with the Geospatial Platform and data.gov. Any client supporting CSW (desktop GIS, Web application, client library, etc.) can integrate the new Geoplatform.gov / Data.gov CSW endpoints.
The CSW endpoints support the OGC CSW 2.0.2 standard as well as the ISO Metadata Application 1.0.0 Profile. The response is transmitted as XML conforming to the ISO or Dublin Core metadata schemas. Brief, Summary, and Full responses can be requested, delivering different amounts of information to the requestor based on these common standards. API documentation is available under Resources on the Geoplatform.gov site.
