4. GENERAL REQUIREMENTS
4.1 Preparation of DIDs.
DIDs (see Figure 1) shall identify the content and format requirements for data to be prepared for use by the Government under the terms of a contract only when there is not an existing DID listed in the AMSDL that is adequate, as is or with tailoring, to define the required data product. A DID shall cover a single deliverable data product. If a single work task generates more than one deliverable data product, a separate DID shall be selected or prepared for each.
4.2 DID structure.
Two methods are authorized as follows:
A self-contained DID is a complete description of the data content, format, and intended use without reference to other documents. A self-contained DID is preferred because it reduces the number of referenced documents.
