KDM.Source extension : a metamodel for weaving Code models and KDM Inventory models

The component proposes a small framework for building weaving information between code models (Java, C++, ...) and physical resources (disk files and directories).

This framework reuses the KDM "Source" subpackage, which proposes a model for physical resources, known as "Inventory Model" (see figure [here])

KDM inventory model also proposes SourceRegion/SourceRef concepts for weaving other kdm models (kdm code models, ...) with physical representation. Some references exist from other KDM subpackages to the SourceRef concept.

KDM Source Metamodel (from the KDM Specification v 1.1)

MoDisco proposes to compose KDM inventory models with non-KDM models. For technical reasons (generic reuse), a new metamodel extending KDM Source has been created.

A subpart of KDM Source model is extended for linking the SourceRegion concept with non-KDM elements, via the ASTNodeSourceRegion metaclass.

Moreover a recurrent pattern, in such a model composition, is to link KDM SourceFile with a code model element. Such a link is represented with CodeUnit2File metaclass.
