This is a fascinating project. Have the original developers lost
momentum on it since March 2007?
Still there is some re-organizing ongoing in the teams. However, we are
still further developing this software. We have some new features
already and some are still in the pipeline.
MDDi is backed-up by a European research project Modelplex
(http://www.modelplex-ist.org/) which will contribute to MDDi for the
upcomming 2 years. Soon there will be substantial updates on the project
web-site etc. So please stay tuned.
