Reference Models and MDGs
EA MDGs (“Model Driven Generation”) are the way that Sparx implement new modeling languages.
To do this, they follow the way that UML (Unified Modeling Language – the basis of most of what EA does) describes how to make new languages. It does this with a set of rules and structures, that describe what links of ‘thing’ a user can create using the new language, and how those things can be connected and drawn on diagrams.
Sparx EA has lots of free and paid-for MDGs, for different modeling languages, and some are built-in to the EA product.
The capabilities of EA MDGs and Model Expert Reference Models are different, although there is some overlap in their functions.
- Model Expert has lots of functions to help modelers
- The EA MDG focuses on implementing all the details of a modeling language
