Establishment of the Internet and rapid adoption of the World-Wide Web has led to the definition of standards for the electronic exchange of many types of information.
Other science disciplines (including mathematics, chemistry and biology) are moving toward data exchange standards, based in part on a Web technology known as Extensible Markup Language or XML. These standards allow rapid dissemination of molecular models, DNA sequences, and mathematical descriptions.

A 2002 American Institute of Aeronautics and Astronautics (AIAA) paper estimated potential savings of over $ 6 M in productivity gains and reduced simulator down-time for a single aircraft type in one year from adopting a standard distribution medium for vehicle model updates.

An AIAA standards working group has developed an "application," or grammar of XML to support the exchange of aircraft simulation flight dynamic models (some simple examples are found here). The Dynamic Aerospace Vehicle Exchange Markup Language (DAVE-ML) follows draft AIAA standards for simulation axes systems, variable names, and function table data descriptions. The draft is now undergoing public review.

A reference manual for the latest development version of DAVE-ML can be viewed on-line here or downloaded as a PDF file here (about 300 KB).

DAVE-ML improves simulation productivity
within collaborative teams

DAVE-ML ensures rapid and accurate aero model exchange with automatic verification

The DAVE-ML project goal is to develop an XML application to encode complete flight vehicle dynamic models in a facility- and language-independent, consistent way, to expedite model exchange and validation between different simulation facilities and tools.

Motto: "Rehost in minutes, not months!"

The development of DAVE-ML is an informal, cooperative effort between government agencies and aerospace industry representatives via the AIAA Modeling and Simulation Technical Committee. Current voluntary participants include NASA Langley Research Center, Australia's Defence Science and Technology Organisation, and SAIC, Inc.. Other interested parties include NASA Ames Research Center and U.S. Naval Air Systems Command.
