[tdwg-tag] darwin core terms inside tdwg ontology

[Roger Hyam]

Hi Markus,

My plan is to produce an abstract model (a text description of the  
classes and properties) and a series of example concrete models. One  
would be the OWL ontology (perhaps this would be normative not sure  
yet) another would be a CSV file format and a third would be a simple  
(one namespace) XML file format. I will define mappings between all  
these (possibly XSLT to get from XML to CSV and OWL).

I also plan to do a mapping from the IPT checklist format to one or  
all of these things.

It would be good to write a couple of tools to do some auto conversion.

If I cut out all the rubbish and only include what is actually used we  
are only talking two classes and < thirty properties so I should be  
able beat the thing into submission quiet quickly.

All the best,

Roger
