Sample for Connector with IATP

[anlam]

I was wondering if there are any running examples of Connector with the identity hub. I attempted to run the MinimunViableDataspace on the mvd-with-iatp branch but did not succeed. Specifically, while the consumer was able to request the catalog, negotiations failed to commence due to a verification error.

while IATP is already very mature, in fact it is being used in several data space endeavours, IdentityHub is not quite there yet.

We will provide an MVD with IATP plus samples once it's ready. Unfortunately we are unable to provide any guidance and help at this point, because there are too many moving parts still and we have limited resources. The mvd_with_iatp branch is very likely lagging behind quite a bit, since we only sporadically update it.

Hi @paullatzelsperger,
Thank you so much for the information. After fixing some errors in the mvd-with-iatp branch, I am able to initiate negotiation on asset-1 (which requires the PcfCredential of the consumer). I noticed that the producer was able to retrieve the PcfCredential of the consumer from its IdentityProvider and issued a ContractAgreementMessage back to the consumer. However, upon receiving the ContractAgreementMessage, the consumer also requested the PcfCredential of the provider, which resulted in verification failure because the producer does not necessarily have a PcFCredential.
Is there something that I have missed from the negotiation process?

IIRC that was a bug we had a while back, but it should be fixed already. MVD still uses 0.6.1-SNAPSHOT of EDC, which is quite dated.

you can check out this latest commit where I upgraded to EDC 0.6.5-SNAPSHOT
