instance values look more like identifiers... #57

Closed thomas-fossati closed 3 years ago

thomas-fossati commented 3 years ago

Is value in instance-value-group-choice the right name? All of these (except for, maybe, IP addresses) look like proper instance identifiers.

In light of #51, which adds an element value to the instance object, we should probably revise this.

In particular, ISTM that we could give "instance claims" a more uniform treatment by making them a sub-case of the already existing endorsed/reference-claims pair.

I don't have a strong opinion. I think both are correct semantically. You would have to do differential privacy analysis to know just how unique the instance value is. What would be the threshold of uniqueness that changes an instance value to an instance identifier?
