[tdwg-content] Darwin Core Proposal - term content recommendations to comments

Using a property from a well-known vocabulary like SKOS would be good.  
But there is the problem that Bob mentioned.  Also, I'm not clear about 
the entailments that would result from skos:note and skos:example being 
declared as annotation properties. [1]

I think that the intention of the RDF guide was that as new properties 
were added to DwC, they would be birthed simultaneously in both the 
IRI-object and literal-object versions without necessitating a change to 
the guide itself.  Whether that is allowed technically, I don't know.  
When we add terms to the normative DwC document, they show up in the 
non-normative documents of the standard (e.g. the quick reference guide) 
without additional action.  If that's not a problem, then adding them to 
the list in the RDF guide also should be able to happen routinely. 

This is a good topic for the vocabulary maintenance task group 
(currently in the process of formation).
