RE: [EXTERNAL] Re: Fwd: Protocol for requesting private data?

I think we should consider the multitude of cases where you want to grant access to a preference or some other type of data that changes over time, such that the party you want to have the info is able to see its latest state over time. For this, basic credential exchange won’t suffice, unless we want users inundated with endless mobile notifications as entities attempt to ascertain the current state of the preference you wanted them to know about. An example would be sharing your shipping address for UPS, Fedex, etc., because people often move, or what type of music you are most into presently, because your go to playlist changes composition.

And, as Many had hinted at by referring you to the credential handler API, this sort of problem is what verifiable credentials are great for, rather than DIDs.

Yes, several. One is the Credential Handler API:
