Expiration versus Revocation

[rvarn]

When a claim issuer limits the duration or similar condition for use of a claim it should be considered an expiration. This could include something as simple as the time for which it is allowed to be used or a business model requirement like the subject has a current paid subscription, attending X hours of continuing education, or a membership that includes the claim as part of that business model. An expired claim can be known to have existed like license a subject once held but no longer has or is no longer in current issuance. That would allow resume like uses of past claims that have expired.

Revocation would be when some aspect of the validity of the claim has failed such as discovered fraud by the subject, faulty evidence or theory on which the claim was based, a compromise of the security of the claim, misuse of the claim in violation of the terms of issuance, and so on. A revocation would remove the claim from be asserted by anyone and disallow referential uses in resumes or similar use.

I've done a lot more thinking about this from at least the perspective of BTCR.

After some more feedback on this user story / use case and it feels a bit more complete I'll post at least to a link to it here and in vc-use-cases.

Chairs believe this has been addressed. Closing.
