Project: unAPI

unAPI [1] is an open specification to simplify movement of information across web applications. From revision 1 of the unAPI spec [2]:

"Background

unAPI is a simple website API convention. There are many wonderful APIs and protocols for syndicating, searching, and harvesting content from diverse services on the web. They’re all great, and they’re all already widely used, but they’re all different. We want one API for the most basic operations necessary to perform simple clipboard-copy functions across all sites. We also want this API to be able to be easily layered on top of other well-known APIs.

Objective

The objective of unAPI is to enable web sites with HTML interfaces to information-rich objects to simultaneously publish richly structured metadata for those objects, or those objects themselves, in a predictable and consistent way for machine processing."

See the most recent version of the spec, linked above, for details on how to participate in the development of unAPI.
