[tdwg-content] Conflict between DarwinCore and DublinCore usage of dcterms:type / basisOfRecord

That sounds like a good solution to all of the problems. I would
propose that the basisOfRecord IS the the same thing as your proposed
dwc:subtype, so we should keep basisOfRecord.

Net solution:

1) keep dcterms:type
2) use DCType vocabulary to control dcterms:type (so, StillImage,
PhysicalObject, Event, etc.)
3) keep basisOfRecord
4) use our DwC-specific subtypes (PreservedSpecimen, FossilSpecimen,
HumanObservation, etc.) as the controlled vocabulary for basisOfRecord
without a formal type vocabulary (very close to how it is now, just
some of the terms would go to dcterms:type).
5) add a recordClass term
6) use the DwCType vocabulary to control the recordClass term instead
of the dcterms:type term.

This solutions fixes the Dublin Core - Darwin Core controlled
vocabulary problem, retains all existing terms, isolates the
controlled vocabulary that is specific to our domain, making it very
easy to expand without changes to the standard.

Any objections?
