Thanks, I’ll look into those topics. In the US, it’s looking like non-anonymous for legislator feedback is common (e.g. https://www.sanders.senate.gov/contact/comment). At some point, we might be devising schema for credentials. With electoral districts, examples could show how cities, electoral districts or states could be provided as a commenter may be provided the option to remain anonymous. What does the group think about, at some point, a feedback form example, for elected officials’ websites? The Credential Handler API and related API’s may augment or replace portions of HTML forms.

Any derived attribute that can be expressed as a mathematical formula (e.g. over 21) could be exposed privately. I think the "selective disclosure" body of work deals well with such derived attributes.

Yes indeed. This would be a suitable credential for (in the UK case) a local authority to issue to a resident regards David > > > Best regards, > Adam > > *From:* David Chadwick <mailto:D.W.Chadwick@kent.ac.uk<mailto:D.W.Chadwick@kent.ac.uk>> > *Sent:* Wednesday, August 23, 2017 5:43 AM > *To:* public-credentials@w3.org<mailto:public-credentials@w3.org> <mailto:public-credentials@w3.org<mailto:public-credentials@w3.org>> > > Hi Adam > > since credentials are signed by issuers, then I do not believe a > repository can implement a derived attribute, as a repository is not > usually a trusted issuer.
