Last fall, NTEN hosted a discussion amongst some of the major vendors in about Open APIs, one of the major pieces of the data integration puzzle. One year later -- almost to the day! -- two major vendors have announced major initiatives around Open APIs. Coincidence? We think not!

Last week, Kintera announced the expansion of their Connect program, adding APIs to their library of tools.

The latest announcement is from Convio, which today launches Convio Open. The site addresses data integration in three ways: APIs, Connectors, and Extensions. It's a much deeper set of tools than what we've seen before, and the site provides integration resources for organizations with a variety of integration needs, including a FaceBook integration.

Who's next?
