*Description*

An abstract composition definition is a definition of a composition that is independent of the type of components. It describes the components in the composition, the relation between components, the structure of the composition, and it contains URLs to locations where different component types are stored.

Types  of components can be _build-level_ components, _source files_, petri nets, etc.

*Example*

Below is an example of an abstract composition definition for the composition described at KoalaCompiler.
