[tdwg-tag] Embedding specimen (and other) annotations in NeXML

[Hilmar Lapp]

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:
1) Is this using DarwinCore in a correct and/or sanctioned way?

2) 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?

3) 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) 
.

4) 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!

Cheers,

	-hilmar
