Re: Schemas or Models of Credentials and Issuers

David,

Thanks. I agree that we will need extensible ontology. These ontology and digital wallet querying topics are interesting to me.

Also, the capability for websites to version their account verification processes, in particular as issuers emerge, users perhaps verifying their accounts more than once, is an important topic. Such versioning would include versioning the digital wallet queries which could adjust the credentials available for use in the user interfaces of digital wallets for users to compose verifiable profiles from.


Best regards,
Adam

Hi Adam

I envisage that an ontology will be needed, and that the CCG could
define a generic global ontology (cf X.500/LDAP) whilst communities of
users will define their own application specific ones to supplement the
global one
