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
per 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 the ANSI/AIAA S-119-2011 standard for
simulation axes systems, variable names, and function table data descriptions.
A reference manual for the latest release 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!"
- October 2011
An update was given to the modeling and simulation community on the new
ANSI/AIAA S-119 standard and it's possible financial benefits was given to the
2011 MODSIM conference in Virginia Beach, VA. Slides are available here.
A formal NASA report detailing the results of an assessment of S-119 sponsored
by the NASA Engineering and Safety Center has been released as a two-volume
report; see the Papers page for more information.
- July 2011
Version 2.0.2 of the DAVE-ML DTD and reference
manual is now available. This includes some textual changes in the reference
manual (for version 2.0.1) and a slight reordering of the DTD ENTITY
declarations (for version 2.0.2).
- March 2011
Version 2.0 of the DAVE-ML DTD and reference
manual is now available.
On March 22, 2011,
the draft AIAA
standard received final publication approval
by the American National Standards Institute. It
download by AIAA members and can be ordered
by others for a nominal fee.
- February 2011
On February 18, 2011, the draft AIAA
standard received final approval by the AIAA
Standards Executive Council and will soon be submitted to ANSI.
Updated the Future Plans page to reflect a better
roadmap, thanks to Geoff Brian's coaxing.
Updated the DAVEtools web
page; this Java package for exploring DAVE-ML is available as open source from
- January 2011
The US 1976 Standard Atmosphere is available in
Version 2, Release candidate 4 of the DTD can be found on the DTD page. Changes are the result of recommendations from
an internal NASA assessment of the draft AIAA
standard (including DAVE-ML) and include mandatory IDs for all defined
tables and support for limiting variable ranges.
- December 2010
Second public comment period on the draft AIAA
standard ended Dec. 29. Awaiting news from AIAA on any received comments.
