The RDF "market" is the amount of money organizations are spending on RDF 
technologies.  This includes the companies Phil mentioned, which btw are 
not using RDF databases exclusively.  The same organization are also using 
traditional databases and unstructured repositories too, and probably 
their RDF use amounts to less than 5% of their total overall data storage.

I am not disputing that there is RDF adoption.  Nor am I disputing that 
RDF is a great solution for some data needs.  I am simply providing 
evidence that RDF is so far a very minor database technology and when we 
base our Best Practices recommendations ONLY on RDF we are creating 
standards with very minor impact.

This may not be what people want or like to hear.  But it is what the 
market is so far telling us and I think it behooves us to listen.

What is "the RDF market"?

I'm having trouble understanding that statement when Phil has pointed
you at a lot of examples of government and non-government deployments
of RDF that are Open Data.

Are you talking about RDF triple stores rather than people using RDF?
