ISSUE-11: Does every permission/prohibition need to have both an assignee & assigner?

parties of perm/proh

Does every permission/prohibition need to have both an assignee & assigner?

State:

CLOSED

Product:

POE - Information Model

Raised by:

Simon Steyskal

Opened on:

2016-11-08

Description:

The current spec states (comments inline; similar for prohibition):

> 3.4 Permission
>
> The Permission entity indicates the Actions that the assignee is permitted to perform on the associated Asset.

It is not required for perm/proh to have any party assigned.

> In other words, what the assigner (supplier) has granted to the assignee (consumer).

I would argue that not every assigner/assignee has the role of a supplier/consumer.

> [...]
> Party: the Permission MUST refer to one or more Party entities linked via the Role entity (see Section 2.3.1) (OPTIONAL)

Is it possible to combine MUST and OPTIONAL?
