[tdwg-tag] string literals vs. uris for dwc:recordedBy, dwc:identifiedBy, and dwc:georeferencedBy in RDF

[Peter Ansell]

That isn't correct RDF/XML as far as I know, but the following two
options are...

<dwc:recordedBy
rdf:resource="http://people.vanderbilt.edu/~steve.baskauf/foaf.rdf#me"></dwc:recordedBy>
<rdf:Description
rdf:about="http://people.vanderbilt.edu/~steve.baskauf/foaf.rdf#me"><rdfs:label>Steve
Baskauf</rdfs:label></rdf:Description>

and (because the ontology doesn't tell you URIs are required)

<dwc:recordedBy
rdf:resource="http://people.vanderbilt.edu/~steve.baskauf/foaf.rdf#me"></dwc:recordedBy>
<dwc:recordedBy>Steve Baskauf</dwc:recordedBy>
