6.2 Data model

To understand how to build models as well as reuse and link design information between models you should know something about the higher-level structure of the repository, i.e. the data model. In this chapter we describe the underlying data model.

	How the various tools of MetaEdit+ manage that information.
	How generators retrieve information from the repository.
	How new modeling languages can be implemented into MetaEdit+.

In the following the structure of the data model is explained with eight general rules.
