An important part of smoothing the way to success in creating your own DSM
solution is good tooling. It is possible to create your own modeling tool from
scratch using graphics frameworks and so on, but for all but the largest groups of
developers such an approach will be prohibitively expensive and time consuming.
There are currently several DSM tools available that will allow you to simply
xiv PREFACE
specify your modeling language, and which offer in return a modeling tool for that
language.
The authors have played a central role in the development of one such DSM tool,
MetaEdit+. The earlier MetaEdit was created as a research prototype in 1991, and
released commercially in 1993, being the ?¬?rst tool to allow people to de?¬?ne their
modeling languages graphically. As is common with such ?¬?rst versions, the original
architecture was found to be too limiting for large-scale commercial use, lacking
support for multiple simultaneous modelers, multiple modeling languages, and
multiple integrated models. These and other requirements were met in MetaEdit+,
released commercially in 1995. MetaEdit+ was created from a clean slate, but
building on the experience gained with MetaEdit: a prime case of ??????build one to
throw away.??™??™
This book, however, like DSM itself, is not limited to or focused on any particular
tool.
