A web service interface to search metadata catalogs. With the funding of the GIN project, and its dependency on existing (GEON, NGMDB) or soon to exist (NGGDPP) hosts for catalog/discovery services, the specification for how catalog services will work is a high priority for community convergence. There are many benifits to the community offered by a standardized approach to registering and discovering geoscience information resources.
Discussion at the GIN kickoff workshop in Houston, and at a subsequent meeting with Steve Richard, Ashraf Memon and Kai Lin at SDSC, indicated that the Open Geospatial Consortium (OGC) Catalog Services for the Web (CSW) specification (07-006r1 Catalogue Services Specification v.2.0.2 ) offered an existing specification for catalog services that could meet requirements of all the interested parties.
