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 v1.1. Ideally, the response format should be useful across OpenSearch, DataCasting, and ServiceCasting responses.

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.


Use the Talk:Discovery_Cast_Atom_Response_Format_v1.1 to openly discuss the proposed specification.
