[tdwg-content] Proposed new Darwin Core environmental terms from ENVO

Thu Sep 26 02:44:19 CEST 2013

I was assuming that the proposal was that subclasses of envo:habitat would take the place of values for the dwc:habitat property. But perhaps I was naive or misunderstanding?

If I am understanding the proposal correctly, the proposal is to replace the term <http://rs.tdwg.org/dwc/terms/habitat> (i.e. dwc:habitat) with the term <http://purl.obolibrary.org/obo/ENVO_00002036> (which I'll call envo:00002036 for brevity)  However, the definition of dwc:habitat which you can view at http://code.google.com/p/darwincore/source/browse/trunk/rdf/dwcterms.rdf says

Even if we weren't talking about RDF, I'd still have the same problem (we are changing a property into a class) - it's just easier for me to make plain what the issue is by giving RDF examples.  So just exactly what can I "do" with envo:00002036 ?????

This particular issue is a case of a broader issue that I have about OBO-style ontologies.  They are great for defining how many, many kinds of classes are related to each other.  But they provide very few properties that could be used as predicates to serve as properties of instance data.
