DoD Discovery Metadata

Overview


This XML Data Encoding Specification for Intelligence Content Discovery and Retrieval (CDR) defines detailed implementation guidance for using result sets in service responses applicable to the IC and Department of Defense (DoD) and information produced by, stored, or shared within and between the IC and DoD. The Content Discovery and Retrieval (CDR) Search Component specifies the use of result sets in service responses. As the DoD Discovery Metadata Specification (DDMS) is the Intelligence Community (IC) and Department of Defense (DoD) standard representation for resource metadata, and the IC Information Resource Metadata (IRM) standard is a supplement to it, providing guidance on how to search for DDMS and IRM encoded data is important. This document provides implementation guidelines for the use of DDMS and IRM in query request expressions and query responses for the CDR Search Specifications.

This is the first release of the specification and therefore provides no backward capability.

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 Data Coordination Activity (DCA) and Content Discovery & Retrieval Integrated Project Team

Mission Requirements


This specification is designed to fulfill a number of requirements in support of the transformational efforts of the Intelligence Community. Many of these requirements are articulated in IC Directives.

This specification includes design features capable of:

  • Use of result sets in service responses.
  • Provides guidance on how to search for DDMS and IRM encoded data.
  • Provides implementation guidelines for the use of DDMS and IRM in query request expressions and query responses for the CDR Search Specifications.
  • Defines joint vision and shared oversight between IC and DoD.
  • Outlines IC/DoD CDR IPT set of architecturally-driven standards and specifications that enable content discovery and retrieval of all IC and DoD data assets.
  • DoD Metadata Working Group
  • CDR Reference Architecture (CDR-RA)
  • Advises on how to search documents which follow the DDMS and IRM specifications.
  • Uses XPath as the notational convention.
  • Defines dependencies
  • Defines Version and XML Namespace Policies
  •  Provides info on running examples written in DDMS 5.0 to make work with DDMS 4.1 examples.
