OpenSearch is a collection of simple formats for the sharing of search results.
The most recent version of the specification is OpenSearch 1.1 Draft 6.
This respository is a migration of the opensearch.org website. The raw export files can be found in the src/ subdirectory, the extracted wiki text can be found in the mediawiki/ subdirectory, and a cached copy of the html can be found on archive.org.
The specification has been unchanged and stable for over a decade, and is unlikely to change again. However, if you see a problem or want to suggest a modification, please open an issue on the issue tracker or fork the repository and send a pull request.
The community list can be found at https://groups.google.com/d/forum/opensearch.
