Oh ok, I didn't know that, thanks!

First, I wanted to leave things like the interpretation of an 
"established vocabulary" open to the reader. But as it is a diploma 
thesis, I was asked to make clear definitions for the indicators which 
wouldn't leave much room for interpretation.

Yes, media types, which are stated in an HTTP-answer in the 
"Content-Type"-header. I took this indicator from the Weaving the 
Pedantic Web paper, which includes the example of stating the 
Content-Type of an RDF/XML-document as 'application/xml', although the 
actual type would be  'application/rdf+xml'.

It's a practical way to determine it (which I can use for the 
implementation of the formalism). Another way would be to compare many 
documents from many data sources and to find out, which vocabularies are 
most popular.

I must admit, I forgot about these two. I'll add them!

Thanks again!
