Thread-topic: Discussion on the DCP Issuance Flow: Credential Issuance on the Basis of Another Credential

Dear DCP Committers,

in regard to Issue #255 (https://github.com/eclipse-dataspace-dcp/decentralized-claims-protocol/issues/255), I would like to discuss my approach to support the presentation of an existing credential within the DCP Issuance Flow. I think this flow is essential for future automated data space onboardings and should be supported by the DCP (e.g. automatically issuing a data space membership credential on the basis of any existing VCs in the organization's wallet), especially in regard to the upcoming eIDAS 2.0 regulation. To this end, please take a look at the sequence diagram attached to this mail.

I am happy to either discuss my approach in a dedicated meeting with the DCP committers or within our next DCP weekly meeting. I would really appreciate your feedback on whether this is compatible with the current DCP Issuance and Presentation Flow.

Kind regards

Niklas
