Feature agera-edc/MinimumViableDataspaceFork#100 After agera-edc/MinimumViableDataspaceOld#57, agera-edc/MinimumViableDataspaceFork#95. agera-edc/MinimumViableDataspaceFork#77

Description

As a dataspace participant I want to have my policies enforced to ensure that my assets are only used for the intended purpose.

The following policies shall be supported (Update supported policy list after spike agera-edc/MinimumViableDataspaceOld#57):

• Access for only one specific dataspace participant (other participants shall not have access)
• Access with an expiration date

Note: this story only covers a small selection of policies that can to some degree be technically enforced and are already supported by the EDC. Subsequent work on policies will be covered by dedicated feature agera-edc/MinimumViableDataspaceFork#100.

Acceptance Criteria

• [ ] Example policy definitions are available in the MVD documentation
• [ ] Policies defined above are enforced upon contract negotiation and data transfer
• [ ] Documentation on how to check whether policies have been enforced with examples for the defined policies

Tasks

• [ ] Document example of all supported policies in MVD currently and how to check if a policy was enforced.
• [ ] Verify supported policies are enforced as expected. (Can be part of System Test or more lower level tests.)

Ben shared the following code he built (and validated) to implement a sample policy:

As EDC doesn't have support for all listed policy requirements here. Should we first create a separate EDC implementation issue in its repo and then take this one from MVD UI/documentation perspective?

@cpeeyush Let's start with policies that are already supported and adapt the description of this story accordingly. We will then add support for additional policies as part of feature agera-edc/MinimumViableDataspaceFork#100. The goal for this story will be to figure out which policies are already supported and create examples for them.

Putting this story on hold, as adding additional policies are currently not a priority.
