There's been a recent surge in development of tools that allow you integrate between multiple Domain Specific Languages (DSL) - tools that I refer to as language workbenches. Much of the discussion around language workbenches is very similar to the discussion around the Object Management Group's Model Driven Architecture (MDA). In my view the MDA means different things to different people - and this effects how we view the relationship between MDA and language workbenches. Certainly there groups of MDA practitioners who are using MDA ideas to build a language workbench. However my feeling is that the help MDA provides is partial, at best. A broader school of Model Driven Development (MDD) echoes many of these ideas without the links to the MDA standards - this is something that is very much in line with the ideas of a language workbench.
