Investigate for provenance other standards (dublin core)

[jamoore]

As discussed during #7843, much of what is currently stored as "experimenter" or "group" is actually provenance information that cannot be imported directly to the server.

Previous versions of the server would create users and groups as needed. This no longer happens for security reasons, and therefore this information is more or less ignored on import.

If instead, we were to store, say, a structured annotation containing a block of dublin core or similar with who created the file, when, what license it's under, etc., then this information would be stored in the DB and re-attached on export.

This would allow us to move many of the ome.xsd types/properties like user/experimenter/leader/contact out to omero.xsd or remove them outright, and would provide a more flexible, extensible way for users to express the provenance of their data.

Note: this may also be the appropriate place for info like "Image.format", including not just the reader used by Bio-Formats as currently, but also the software version, the JVM, etc. etc.

Moving to 4.4.1

This is certainly still an option but no investigation took place. New tickets should be opened for specific tasks if desired.
