Remove assets after testing file transfer

[veronikasiska]

Dear Community, I have some trouble with implementing a clean-up for a file transfer end-to-end test. The initial idea was to clean up all resources (assets, policies, contract definitions) using EDC, but the asset can not be removed since it is associated with a contract agreement. I do not see a way to remove a contract agreement via the management API.

Am I missing something? Or is it intended that once an asset has been part of a transfer, it can not be removed any more?

Many thanks in advance for the help!

it is intended, a Contract Agreement is a fact that happened and currently there's no way to delete one.

Thank you for the answer! That part is clear (that the contract agreement can not be deleted). Still, is it intended that once an asset has a contract agreement associated with it, it can never ever be deleted again?

It's about consistency, as you said the asset is associated with the agreement, so deleting it would cause data inconsistency.

That's perfectly understandable, but does not seem very realistic from the perspective of a provider. I expect to be able to remove offers and assets, even if they were subject of valid contracts before. There could be constraints to ensure that data consistency is retained, but I can imagine cases where this could be done in a consistent way; e.g. the policies attached to all contract agreements for that asset have an expiration date that lies in the past.

What do you think? Has this been discussed before?

Yes, you can implement a collector that transitively determines which assets no longer reference in-force contracts and remove them. Since this is use-case specific, it should be handled as a customization.
