The OpenSearch 1.1 specification

I just installed a recent Vista build on my dev box, and I noticed a new set of options to add a custom search engine in IE 7. Which got me digging. For your browsing pleasure, here are some links:
This page describes the current list of providers, and what else needs to be done on the missing providers. The requirements are simple – the search engine must support queries based on the OpenSearch 1.1 standard.
– The IE blog contains a little bit of history around Amazon and Microsoft working together on this standard.
– The A9 developer blog also contains some interesting details.
