TMDD & MS/ETMCC Guide: Standard for Functional Level Traffic Management Data Dictionary (TMDD) and Message Sets for External Traffic Management Center Communications

These draft standards are intended to work together to provide a high level of interoperability among regional and local traffic control centers. They provide consistent names, definitions and concepts similar to spelling and parts of speech to world-like data elements; traffic control concepts are enabled to be defined and used in the same way by different systems and centers. Provision, however, is made for each center to have its own unique messages.
