We are doing the same thing with our Linked Data middleware (Sponger 
Cartridges).

Yesterday we delivered item one for anyone to use (including Micheal and 
Co. re. schema.rdfs.org).

Next we just finish the job as we did with Google Vocab two years ago.

The beauty of Linked Data is that it cannot be held hostage by anyone :-)
