Re: Vocabulary Usage on Web Pages - Analysis Results

Hello Hannes

Interesting stuff. Among top namespaces I see
http://rdf.data-vocabulary.org/
I must admit I did not know it ... and looking at
http://data-vocabulary.org/ it seems that it has not been updated since
2010, and it seems to me widely redundant with, or prefiguration of
schema.org.

@schema.org folks : Since http://data-vocabulary.org/ seems to belong to
Google, would not it be a great idea to have a note on this vocabulary
along the lines of ... this vocabulary is obsolete, use schema.org instead?

Or do I miss something?
