Another use case for issuer's TOS, from the mailing list:
Claimants present claims. That's simple. Authentication, delegation, and proving right to use, are external to the claim.
There is one exception that I can see, where an issuer includes a TOS clause that explicitly affords the right to be a claimant to a specific entity--which may or may not be the subject. In fact, I think that's a fairly useful TOS: this claim only applicable when presented by the subject as authenticated by procedure X.

I see two different 'terms of use'. The first is the policy of the issuer. This states the restrictions on the use of the VC by the subject, and the inspector should honour this policy. If the inspector disregards this policy then the issuer will take no responsibility for this i.e. the risk from use of the VC is entirely upon the inspector.
The second 'terms of use' is that of the holder when he/she presents the VC to the inspector. An example might be 'I want you to use my address in the VC in order to post me the item that I have just purchased but not to subsequently send me any marketing literature or other junk mail'.
This latter terms of use probably does not need to be in the VC, and could be in the protocol between the holder and the inspector

Hi all, have you looked at:
ODRL Information Model https://www.w3.org/TR/odrl-model/
ODRL Vocabulary & Expression https://www.w3.org/TR/odrl-vocab/
(now entering CR)
The POE WG (listed on your Charter under Liaisons) would be happy to chat more and look into the use case(s) ;-)
from vc-data-model.
@riannella Would you be able to join the VCWG to give a background on POE and ODRL and how we may be able to use it to express things like "consent", "terms of use", and "policy" for Verifiable Credentials?
from vc-data-model.
Yes, that would be fine. What times is the VCWG call? (I am in Brisbane, AU) #41
from vc-data-model.
I think this issue can be closed now since we have a terms of use section in the latest VC Data Model document
from vc-data-model.
Closing, per @David-Chadwick's observation. We will continue to discuss exactly how to express terms of use using ODRL in another issue.
