DIA's Nick Ballenger joins a motley assortment of vendors in what NTEN is perhaps melodramatically billing as The Great Open API Debate.

Have an opinion on the state of APIs – application programming interfaces – or just want to know what the heck all the discussion is about? Then join us this Friday for a live debate between the major players in nonprofit software and find out what’s going on with APIs and what it means for nonprofits.

You’ll hear where vendors on the panel are moving and what the tangible benefits will be for nonprofits. The speakers will also give their opinions on why openness matters and what open APIs mean for the open source movement.

As befits web2.0 chatter, the conference call (tomorrow at 1 Eastern) is to be released by podcast subsequently, and there's simultaneous blog-based conversation besides.

If you've been dying to write your own API calls to the DIA database, bask in our API documentation here.

Update:  As an aside, D.C. types seeking something less technical and more judgment-impairing -- as D.C. types are wont to seek -- are welcome next Wednesday at another of our infamous happy hours.
