Hi Everyone at our mDL conference call today, the group decided that 4 date/time properties are needed for an mDL VC (mobile driving licence VC). These are 1. The date that the driving license was issued 2. The date that the mDL VC becomes valid 3. The date that the mDL VC becomes invalid 4. The date that the driving license expires. Consequently we need 4 properties to represent the above. It quite likely that mDL VCs will be short lived and not revoked. It is likely that other use cases that issue VCs from underlying timed documents may also require the same 4 date/time properties. Therefore it would be useful if the implementation guide could specify these 4 properties (which could then be incorporated into v1.1 of the VC data model). If we had a clean sheet I would suggest the following 4 properties 1. issuanceDate 2. validFrom 3. validUntil 4. expiryDate Unfortunately the current definitions of issuanceDate and expirationDate do not have the required semantics. The proposed validFrom and validUntil properties do appear to have the required semantics, but they do not appear to be defined anywhere. What suggestions does anyone have? Could we add the four definitions to the Implementation Guide? Kind regards David
