There are some best practises to writing and and publishing RDF vocabs. You can find them on the W3C site : 

http://www.w3.org/2001/sw/BestPractices/VM/http-examples/2006-01-18/

I would have a look at how FOAF or some other similar project generate human-readable documentation for their RDF vocabs, I think there is some tool which does it, but I can't recall its name off the top of my head.
