CDR: Atom Results Set


The Content Discovery & Retrieval (CDR) framework enables the use of results sets in service responses. As various service specifications leverage the Atom 1.0 feed syndications format, guidelines must be created to ensure consistent usage across CDR Search REST and SOAP specifications. In addition to the general guidelines for the use of Atom as described at and in Atom 1.0 specification itself, this document extends the base specification to support information requirements in the CDR Search component. The guidance provided in this document focuses largely on the use of Atom 1.0 feed syndication format itself and the general format of commonly used extensions.


This specification supports Intelligence Community Directive 501 (ICD 501), Discovery, Dissemination or Retrieval of Information within the Intelligence Community, which establishes policies for (1) discovery, and (2) dissemination or retrieval of intelligence and intelligence-related information collected, or analysis produced by the Intelligence Community.


Compliance with this specification is measured against all aspects of the technical and documentary artifacts contained within the specification release package. This specification is maintained by the IC Chief Information Officer via the Services Coordination Activity (SCA) and Content Discovery and Retrieval Integrated Product Team (CDR IPT).
