Hey Kingsley,

this is a great demo, thank you! The performance is quite impressive.
However, adding new properties for faceted filtering needs getting used 
to from the usability point of view :-).
This leads me to my question:
Is there a way to access your server and its faceted Data Explorer back 
end functionality by a public Web-service?
Because we are working in the field of HCI and developing graphical 
interface for graph-based faceted exploration of RDF data (see 
www.gFacet.org). So it would be quite interesting to have such a 
high-performance backend!

By the way, I tried to write a comment to the related article in your 
blog but it didn't work out! I got a message that said my comment need 
to be reviewed but it never appeared as comment in the blog. Did you 
receive my comment?

I look forward for your reply.

Best regards, Philipp
