A dataspace participant is identified via its DID document, which serves as the root from which additional information about a participant, like the self-description, can be retrieved.

Acceptance Criteria

[ ] DID documents (dataspace participants including dataspace authority) contain the link to the corresponding self-description.

Tasks

[ ] Add endpoint to serve self-description endpoint.
[ ] Test coverage.

Is this still needed?

In https://github.com/eclipse-dataspaceconnector/IdentityHub/pull/23 we introduced the Identity Hub endpoint serving the self-description.

This GET endpoint has URL: IDENTITY_HUB_BASE_URL + /self-description, while IDENTITY_HUB_BASE_URL is already provided as a serviceEndpoint in the DID document.

So as long as, each DID document contains the URL of the identity hub, then it also indirectly contains the URL of the self-description endpoint.

@bscholtes1A I think this is indeed required for correctness, as it is not mandatory that the self-description document is served by the Identity Hub.
