Allow assignment from actor/role to business object, and from application component to data object

Because assignment is defined as:

The assignment relationship represents the allocation of responsibility, performance of behavior, storage, or execution.

It would make sense to allow:

• Assignment from actor/role to business object to express that someone is a data owner/steward/custodian for some specific data.
• Assignment from application component to data object to express that the application is the repository/golden source/single source of truth for some data.

This would (btw) echoes to the assignment from Node/Device to Artifact to express where the data is stored.
