Hi Stuart,

after reading so many MS documents about DSL and watching your  movie still it is hard for me to get the full big picture of the technology.

you know that a perfect DSL tool should create final codes with minimum meta data and give the developer maximum customization possibility without loosing anything after re-generating code.

First of all, you need diffrent UI tools to see your model. the current default designer is not enough for all scenarios. and some times a Tree and Grid view is a perfect  media to show and  modify the model.
I know about DSL powertoy but DSL designer needs some basic default editors in place without asking users to add their own editors.

There is a company named MetaCase that they are making DSL tools for a while.
they have a good feature matrix  to  compare  DSL tools.
this is the page:
http://www.metacase.com/mwb/tool_comparison.html

Could you please compare MS DSL Tachnology against this matrix?

I beleive this feature matrix is an excelent thing to compare DSL tools.

Thanks
