In a similar vein as Bob mentioned (below), I would like to see how
this
proposal would be applied to the specific case where images taken
directly of living organisms are used to document occurrences (my
original issue posted on the MRTG wiki,
<a class="moz-txt-link-freetext" href="http://www.keytonature.eu/wiki/MRTGv08_Type_term_inconsistent_with_DwC">http://www.keytonature.eu/wiki/MRTGv08_Type_term_inconsistent_with_DwC</a>).
I routinely collect this kind of image and
have made the case that live organism images can and should be used in
the same way as physical specimens to document occurrences
(<a class="moz-txt-link-freetext" href="http://www.cals.ncsu.edu/plantbiology/ncsc/vulpia/pdf/Baskauf_&_Kirchoff_Digital_Plant_Images.pdf">http://www.cals.ncsu.edu/plantbiology/ncsc/vulpia/pdf/Baskauf_&_Kirchoff_Digital_Plant_Images.pdf</a>).
Thus as occurrence records, the metadata for such images should be in
conformity with DwC as well as the media-specific MRTG schema. <br>
<br>
In the example of a live plant image from
<a class="moz-txt-link-freetext" href="http://www.cas.vanderbilt.edu/bioimages/species/frame/oslo.htm">http://www.cas.vanderbilt.edu/bioimages/species/frame/oslo.htm</a> I would
assign image record<br>
<i>DwC:recordClass</i> = Occurrence<br>
<i>DwC:basisOfRecord</i> = StillImage<br>
<i>dcterms:type</i> = StillImage<br>
<i>mrtg:subtype</i> = Photograph<br>
[Note that DwC:basisOfRecord is not synonymous with mrtg:subtype as it
currently stands. Would it have to be under John's proposal?]<br>
<br>
In the example of an image of an herbarium sheet shown at
<a class="moz-txt-link-freetext" href="http://www.morphbank.net/Show/?pop=Yes&id=142009">http://www.morphbank.net/Show/?pop=Yes&id=142009</a> I would assign the
record for the herbarium sheet itself:<br>
<i>DwC:recordClass</i> = Occurrence<br>
<i>DwC:basisOfRecord</i> = PreservedSpecimen<br>
<i>dcterms:type</i> = PhysicalObject<br>
<br>
and for the record of the specimen image:<br>
<i>DwC:recordClass</i> = Occurrence<br>
<i>DwC:basisOfRecord</i> = StillImage<br>
<i>dcterms:type</i> = StillImage<br>
<i>mrtg:subtype</i> = Photograph<br>
<br>
Is this the idea? Again, I note that it is not particularly useful in
this situation to consider <i>basisOfRecord</i> a subtype of <i>dcterms:type</i>
as they have the same value for the images. <br>

<pre wrap="">Gregor,
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?

<pre wrap="">recordClass for Taxon/Occurrence/Event sounds good.
I am less sure about keeping the "perspective-dependent"
basisOfRecord-term in a place where dcterms:type. The dcterms:type
vocabulary is, in principle, extensible, and meant to be extended.
Except, of course, some specific xml-implementation of dublin core
prevent this... To avoid problems with this one might desire to have
only the strict resource type vocabulary in dcterms:type. Then this
could by PhysicalObject/Event and a dwc:subtype added to express
PreservedSpecimen/MachineObservation etc. Essentially, MRTG intends to
use such a mrtg:subtype as well to differentiate different StillImage
or Text subtypes:

This would then mean, DarwinCore might support:
dwc:recordClass
dcterms:type
dwc:subtype
