OK, I think this is fine if basisOfRecord is not supposed to be a 
subclass of dcterms:type.  Then is basisOrRecord considered to be a 
subclass of the new dwc:recordClass that replaces the former DwC use of 
dcterms:type as would be inferred from the "definition" line of 
http://rs.tdwg.org/dwc/terms/index.htm#basisOfRecord ?

These images are geolocated - I just haven't finished writing the 
software to display the location information yet.  My intention 
eventually is to make available all metadata that would be available for 
a specimen AND for an image resource type, hence my interest in both DwC 
and MRTG.

Yes, that helps a lot.  I agree that they should separate records.  I 
have a comment/question related to the issue of relationships between 
resources of these types, but since it's also related to another comment 
as well, I'll attach it to that message.
