Hi Hilmar,
Just a quick answer right now to point you to rdf for the DwC (similar to Dublin Core's rdf) that has just begun the review process as a TDWG Standard.
http://rs.tdwg.org/dwc/rdf/dwcterms.rdf
This is a preview, but I suspect it will not change too much. I'd call your attention to the Sample class as the nearest thing to a Specimen (because it would also be an Observation). Rendered documentation can be found at http://rs.tdwg.org/dwc/terms/index.htm#Sample.
Cheers,
John

Hi Roger and everyone else involved in DwC and the core ontology,
in preparation for the upcoming hackathon [1] here we've worked our way through a number of use-cases for attaching metadata to data elements in NeXML [2] in a way that is semantically defined. The results are here:
http://evoinfo.nescent.org/Database_Interop_Hackathon/Metadata_Support
If you can take a critical look specifically at the section on 'Specimens within collections' (http://tinyurl.com/djdby3) that'd be great.
Specific questions related to that:
Is this using DarwinCore in a correct and/or sanctioned way?
Is there a TDWG vocabulary (in RDF or OWL) that has a relation for
referring to a specimen record, or are you aware of another one that has this?
- I could only find the XML schema for DarwinCore. Are there any
plans for (or did I miss the existence of) a corresponding ontology defined in OWL or RDF, similar Dublin Core (which has a RDF ontology at http://purl.org/dc/elements/1.1 and DCterms ontology at http://purl.org/dc/terms) .
- It wasn't immediately clear how one would use the TDWG core
ontology for doing the same thing in RDF (or OWL) - is this ontology supposed to be used yet, and are there usage examples, or does someone have a recommendation for how one would write the same example using the core ontology?
I know it's a rather tiny subset of DwC that we're using here but that's only a start and one use-case.
Of course, any other feedback to or suggestions for this or any of the other stuff on that page is welcome too!
