Getting started with metadata for internal documents

Hi. I'm looking for examples of applying RDF-style metadata vocabularies 
  to internal documents. Metadata would include version number, type of 
document (not media type, but rather, what its function is eg report, 
template, whatever), status (draft/published) etc. What vocabulary has 
these available?

Dublin Core seems to have some, but not all, and the website isn't great 
  for examples. Any solid collection of examples in this domain (not 
references, examples) would be greatly appreciated.

Thanks,
