I also found this (from the Senate to the House):


which utilizes zip code + 4 to ensure that commenters are from the electoral district of the 1st District of Wisconsin and utilizes a captcha to ensure that commenters aren't bots.

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.

Best regards,

Good stuff!

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
