Message Mapping Design Catalogue v0.8 Excel

PDF (175.9 KB)

The internal technical documentation for the Message Mapping Design Catalogue (MMDC). This documentation reflects the latest design of the overall DCC solution and is aligned with the DCC User Gateway Interface Design Specification (DUGIDS) v0.8 (published 12 September 2014) and the GBCS V.08 specification. DCC has released the MMDC as it believes it to be sufficiently technically stable to assist Service Users to proceed with their own system developments. The updating of this document into a SEC Subsidiary Document is under way (at time of publication) and further details on this process will be published separately.
