Schema needs additional information

[larsvilhuber]

Here are a few things that come to mind:

• PGP Key ID
• PGP fingerprint (both allow to find it in key servers, and compare to publicly posted keys)

Example:

• https://keys.openpgp.org/search?q=admin%40sivacor.org (which fails)

• https://keyserver.ubuntu.com/pks/lookup?search=0xD8BB2071862AFF4A&fingerprint=on&op=index which works, but has the wrong email address (for SIVACOR)

• Own id (e.g,. tro-696d3b46adffb76fef0d83bc.jsonld would have something like { trov:id : 696d3b46adffb76fef0d83bc }
