We've rolled out a great service (www.opencalais.com) that extracts semantic metadata from raw text input - people, places, things, companies, facts and events.

I want to see learn we can make it better. I want to learn how people are thinking about using it. I'd like to have discussions about everything from the technology to the business model to where it fits in the whole semantic web world.

I'll share absolutely openly where we're headed with this initiative, what's working and what isn't, why Reuters is doing this and just about anything else.

So - I'd like a session on "Semantic Plumbing" - what needs to be in place to enable semantic applications quickly. I know Calais is a piece of that. How do we get more linked data resources available? Should we establish a production-strength clearinghouse of linked data assets? What other pieces of the toolkit requite deployment / sponsorship?
