CDF is an ASCII-based format used for describing cyberspace decks and
virtual worlds. This format provides a standard framework that is used to
store, retrieve, modify, and exchange descriptions of cyberspace objects;
including object initialization, state, and scheduling, and cyberspase
simulation.

CDF is based on the CDF format described in Autodesk's Cyberspace
Development Kit. Autodesk's CDF is a closed format used to support a
proprietary deveoper's tool, while the proposed CDF format is an open
format intended to be accepted as an industry standard.
