Please see my slight preference for the word "subtype" over
"basisOfRecord" as a secondary question.

The essence is that I propose to use DublinCore (precendence since
1995 and extremely widely adapted) where it applies.

basisOfRecord is a mixture of DublinCore type terms, and subtypes of
DublinCore terms. In the latter case DwC omits the applicable
DublinCore resource type vocabulary.

Thus any DC-aware consumer of the data has to do both a mapping of
dwc:StillImage to http://purl.org/dc/dcmitype/StillImage  and imply
that the resource quoted throuh PreservedSpecimen, FossilSpecimen,
LivingSpecimen is a http://purl.org/dc/dcmitype/PhysicalObject, that a
HumanObservation or  MachineObservation must be
http://purl.org/dc/dcmitype/Event, and   NomenclaturalChecklist a
http://purl.org/dc/dcmitype/Text.
