A Data Item Description (DID) is a document
that is used to define the format, content and constraints
to which a contract deliverable must comply. A Data Item
Description is normally provided in the contract for
all major deliverables in that contract. Effectively, the should be
a DID for each type of deliverable data. The list
of all data requirements for a contract is called a
Contract Data Requirements List (CDRL). For example, a Data Item
Description might be included for the Systems Engineering
Master Plan (SEMP), the Configuration Management Plan (CMP), the Test
and Evaluation Master Plan (TEMP), and so on. DIDs can
also be called, inter alia, 'model texts', 'templates', or 'proformas'.
