Sorry, to clarify:

This is why we have versioning in the namespaces.


> The foaf vocab is in Testing status, version 0.98. Are they going to change it before it comes out? Who knows?  Will they add something better like foaf:sortName that is more like a traditional library listing?

Yes, the version you'd be using is http://xmlns.com/foaf/0.1/

> Just coming up with a list of all the possible terms out there and fighting over whether they are close enough to use for each term we have will be a major use of time.

I suggest that LoC not do this as it has been done before by the British Library and many others.

> On DC, people you might not be for it, but if we opened the BF vocab up, there might be a lot of clamor for it; it's so simple and it's all over the place!

You'd probably want to version this data too http://dublincore.org/2012/06/14/dcterms.rdf

The syntactic sugar can even be kept in a separate RDF file from the definition of the bibframe properties, making it second class and invisible to everyone who doesn't want it.
