A category whose hom-sets are abelian groups and whose composition is bilinear.

This is an authored directed relation from the source endpoint to the target endpoint.
Give each hom-set an abelian-group structure and make composition bilinear.
Equip an existing carrier or structured object with additional chosen data, when such compatible data exists. Use a construction junction when several independently meaningful inputs must coexist on the same carrier or interact compatibly.
