One-liner summaries of actual changes to make:

dcterms:type.
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 ?
Use cases from Steve: UC-Steve1
- In the example of a live plant image from
http://www.cas.vanderbilt.edu/bioimages/species/frame/oslo.htm I would assign image record DwC:recordClass = Occurrence DwC:basisOfRecord = StillImage dcterms:type = StillImage mrtg:subtype = Photograph [Note that DwC:basisOfRecord is not synonymous with mrtg:subtype as it currently stands. Would it have to be under John's proposal?]

For UC-Steve1, looking at the URL, I see nothing that suggests that the resource at http://www.cas.vanderbilt.edu/bioimages/species/frame/oslo.htm refers to an Occurrence record, but I suppose it is no different from having a specimen with no location information. Nevertheless, if the resource was being described with DwC terms, I would assign: dcterms:type = "StillImage" dwc:basisOfRecord = "Photograph" or "DigitalStillImage" or "DigitalPhotograph" or whatever vocabulary you decide. dwc:recordClass = "Occurrence"
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.
The image would be a different resource that could be referred to by the Occurrence record via dwc:associatedMedia or through an instance of the dwc:ResourceRelationship class. The image resource could be described by the terms: dcterms:type = "StillImage" dwc:basisOfRecord = "Photograph" or "DigitalStillImage" or "DigitalPhotograph" or whatever vocabulary you decide. dwc:recordClass = "Occurrence"
I hope that helps.
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.
