A Collection assembles multiple 'built' items, each with its own development workflow and release identifiers. These complete items are incorporated together into a Collection. Collection components can be any kind of artifact, e.g. a product, an application, some documents, a library, etc.
A collection component is a parent component containing an assembly of both other collections and single components. In MAIA it is represented by a cubes icon.
A collection component may be a mix of single components, other collection components, and external components.
An external collection component is an assembly of external components.
