The more
interesting question is in which areas are there holes in our experience or blind spots in
our understanding.
According to independent industry experts, such as Scott Ambler (2006) and
Markus Vo??
lter (2006), MetaEdit+ is the most mature and sophisticated DSM
environment. A recent independent survey in Europe by MediaDev (2006) revealed
that it is also the most widely known, recognized by over 50% of lead developers.With
customer projects ranging in size up to several hundred modelers and over 10 years of
duration, MetaEdit+ is also widely recognized as having the most experience of DSM
in use. Even so, we still feel there is much to improve and learn: current DSM practice
and tools will face many challenges and choices as adoption spreads.

The Generic Modeling Environment (GME) grew like MetaEdit+ out of an extensive
background of earlier research and practical experience in metamodeling and
modeling tools. The earlier work with MultiGraph Architectures at Vanderbilt had
proved the value of DSM, and created a framework for building new modeling tools.
Specifying the metamodel in textual ?¬?les proved time consuming and inhibited the

evolution of the modeling languages in use. Nordstrom??™s thesis (1999) outlined a
meta-metamodel suitable for de?¬?ning DSM languages in his domain of electrical
engineering, and a Generic Modeling Environment that could be con?¬?gured by ?¬?les
generated from metamodels made with this language.
