The other pressing question is: how do we make sure that vocabularies 
are preserved in a usable way? The one below is available via the 
Wayback Machine at the Internet Archive [1]. You can push files to the 
archive and get a URL returned that represents that snapshot, but that 
doesn't seem to be available via API. [2]

Having an archival "fall-back" URI for vocabularies is going to become 
more and more essential as time goes by. LOV is the canary in that coalmine.

protocol: http://mementoweb.org/
