A Collection is a grouping of multiple 'built' configuration items with their own development process and release identifiers. These complete items are incorporated together into a Collection. Collection components can be any kind of artifact, an application, some documents, or a library.

A collection component is a parent component containing an assembly of collection & single components, represented with a cubes icon.

In MAIA a collection component may be a mix of single components, other collection components and external components.

In MAIA and SBOM Central an external collection component is a assembly of external components.
