I just noticed that a9 has released a second draft of opensearch v1.1. This draft includes details on opensearch autodiscovery for providing a reference to the opensearch description file in an HTML page. This could have a lot of potential for browser plugins. Also, they’ve added a Query element that can be used for echoing back the query that was used to generate results…kinda like the echoedRequest in SRU. These are the things that popped out at me. Of course the big news in the first draft was that Atom can now be used in responses.
