+1, I think this work is slated to start not next week, but the week
after. The week of September 9th.

Yes, it's a concern with this work. Not many people are going to create
a different identity/persona for themselves for each credential that
they hold.

The best solution to this that we've discovered is a legal remedy.
Create a binding digital contract that states that the delivery of the
credential may only be used for X, Y, and Z purposes. For example, my
digital government issued ID may only be used to identify me on the
receiving site. It specifically MUST NOT be transmitted to a 3rd party
for purposes other than verifying who I am. It MUST NOT be used to
aggregate data about me for advertising, spying, etc. purposes.

I'm sure we're going to bikeshed the hell out of 'credential'. My hope
is that we can get that out of our collective system quickly and move
onto the technology. Definitions are important, but discussing them
endlessly does drive people away.

This is an ongoing discussion and should probably be outlined in a W3C
Note or CG publication.

What do you mean by "assessable"?

What do you mean by this?

+1 for 'data safety'

The whole 'rights' thing gets into 'human rights' and arguments about
whether or not the Web is a human right, or access to the Internet is a
human right. We should be careful to avoid those discussions here, those
topics are great perma-thread fodder.
