3.2.1 Ecore Metamodel
The EMF book describes the Ecore metamodel in detail, but here you find a sim-
plified diagram for reference (Figure 3-1), along with some discussion of the
more relevant aspects used as we develop our DSL abstract syntax. It's a fairly
simple model, which is part of its strength. In most cases, you can compensate
for the lack of features in Ecore by using some of the more advanced modeling
techniques, which are discussed in the EMF topic. A longstanding topic of debate
among EMF users is the lack of an EAssociation class, but we don't get into that
here.
