Implementation--they have tested with hospital patients using a fido on a smart phone where service provider creates a policy allowing any combo of credentials and smart phone is a cred repository and app matche which meet the policy and which are missing 15:43:08 David C: need ontology like with top and nested levels like Health Card and what goes under that 15:43:46 q+ to note alignment in thinking w/ what DavidC is saying wrt. ontologies. 15:43:49 q? 15:44:15 while the ontology is external it would be good to start an issue on how to express it in the query format for the credential handler API: https://github.com/w3c-ccg/credential-handler-api/issues 15:44:41 DavidC: eg any student from any university or is it a specific kind of university that is nested under ontological understaning of University.

(I expect he's already moving along those lines) 15:55:44 nathan: one concept raised in various forms--making the ontology from issuer into verifiers language that is unified and brittle for constructs not present in issuers claims so holder may need to reformulate. verifier needs to say what they are willing to accept and how. issuer, holder, and verifier system need to b tied but not have the exact same hierarchical understanding for each to do their part and receive desired value 15:55:58 ack DavidC 15:56:11 q+ to respond to DavidC's ontology discussion - multiple ontologies - data model supports it (and prefers it) 15:57:34 DavidC: re ontology--can be multiple sets of ontologies for each community like banking which would not interface much or at all with health except in minor ways like payment. do not need global ontology but each app needs a mini ontology for that purpose and can use internal mapping to translate the common ontology in indivdual internal representations 15:57:57 ack manu 15:57:57 manu, you wanted to ask nage to just sketch out a protocol exchange in an issue...
