The AADL is a sizable language. Representation of the
AADL meta model as a single unit would
make it difficult to understand and maintain.
The AADL is extensible in that annex-specific sublanguages
can be introduced. The modular meta
model approach allows meta models for such sublanguages to be defined separately in Ecore and
added to the core AADL meta model.
The meta model for the core AADL is divided into six
meta model packages:
Classes in one package of the meta model can be referenced
by other meta model packages. This
is done by preceding the Class name with the package name separated by a double colon (::).
Multiple graphical diagram views have been defined for some of the meta model packages in order
to keep them readable.
The meta model for an initial AADL instance representation
has been defined as a separate meta
model package. Its details are discussed in section Annex C.5. |
