Here's a bit more background on that :

https://www.w3.org/DesignIssues/QuotingURIs.html

Good suggestion, we could put it in pim : contact -- but who owns that
namespace.

Another thought would be to have https://w3id.org/ with webid -- but that
would be less consistent with what's existing in webid

I like nathan's suggestion of creating a new vocab.  Would need to look
into the logistics of publishing and maintenance tho.
