Federated Search Convention
Reuse of Existing Standards
Modification of Standards
Although OpenSearch allows a number of different formats (HTML, RSS, Atom), the ESIP Federated Search convention is to return an Atom response. This is (mostly) intelligible to browser-based newsreaders (the lowest common denominator) while providing a relatively rich structure for parsing as well as accommodating domain-specific extensions.
Time in Atom Response
The ESIP Federated Search convention is to represent Time in the Atom response as Universal (Zulu) time, using the format YYYY-MM-DDTHH:MM:SS[.SSS]Z. Fractional seconds are optional.
