This is a storage key that can be used to retrieve metadata about the credential. Likely for ease of access for displaying. @TimoGlastra likely knows whether we have to keep an equivalent or if this is up to the user to define.

[auer-martin]

The PR is not yet finished. Just pushed some progress

[TimoGlastra]

This is the display / issuer metadata. I chose to not add it as PR in AFJ as the spec is continuously evolving and thus it will contain different structures in the metadata. Not sure if that's a problem. It is very useful to have this though, but it may be better if we can generalize it and create a universal credential display format (not sure what OCA uses for this) with something like https://identity.foundation/wallet-rendering/

[MosCD3]

I am implementing OpenID4VCI in our wallet and in Bifold in the mean time, this PR is a life saver since am not able to use Spheroin for testing with current package version. @TimoGlastra any suggestions on a good testbed (issuer)that supports older draft to use for development until this PR is merged?
For OCA, it will be nice if there is an option to inject an OCA bundle identifier into one of the attributes to use it later for fetching OCA layers for that specific VC. The whole thing is running perfectly in Bifold with the option to remote fetch OCA bundles, the missing part is AFJ handling that as part of credential attributes instead of manually matching with credential/schema ids. Could discuss further

[TimoGlastra]

@MosCD3 for draft 8 you can I think use https://jff.walt.id/ and for draft 11 you can use https://launchpad.mattrlabs.com/

[berendsliedrecht]

Great work @2mau!!! I think there is some cleanup to do, but thats always expected with such a big PR.

[berendsliedrecht]

Still some minor comments, but nothing blocking from my side.
