Specify requirements for ODRL policies (templates)

[jdsika]

EVES-005 defines the process for a contract negotiation. We need to specify the requirements for the ODRL policy. e.g. minimum content and how to verify it.

There are three main types of an ODRL policy:

odrl:Set:

Represents a collection of policies (Permissions, Duties, Constraints).
It is the most general type and is often used to define a policy that consists of several elements.
--> We could use it as a policy template

odrl:Offer:

A policy that describes an offer to use a specific target.
Used when an entity (e.g. a licensor) provides an offer to potential users.
--> We could use this in the context of negotiation

odrl:Agreement:

Represents an agreement between parties that shows formal agreement to the terms of the policy.
--> We could use this as part of the agreement.

Here a policy template as an example:
