Description
At the NASA Earth Science Data System Working Group meeting in New Orleans on October 21, 2010, a proposal was made to expand the scope of Federated Open Search to cover Discovery more generally, thus bringing into the fold datacasting and servicecasting. Therefore a common Atom response format is needed that extends the Atom Syndication Format (RFC 4287) with extensions specific for Earth science data usage. This specification is the outcome of that working session.
Problem Addressed
Currently OpenSearch, datacasting and servicecasting all return very similar granule-level information. But there is no consistent format used. This proposal will provide a specification for a set of Earth science-specific extensions to the Atom response format.
Proposed Solution
See Discovery_Cast_Atom_Response_Format. Note that this link will be changed to include a version.
Rationale for the Solution
Reuse as much of existing standards as possible. Fold in Geo and Time extensions. Define a set of commonly used rel link types for OpenSearch, datacasting and servicecasting.
