OpenSearch

From Wikipedia, the free encyclopedia

OpenSearch is a collection of technologies that allow publishing of search results in a format suitable for syndication and aggregation. It is a way for websites and search engines to publish search results in a standard and accessible format. OpenSearch 1.0 was unveiled in March, 2005. Draft versions of OpenSearch 1.1 were released during September and December 2005.

[edit] Summary

OpenSearch consists of:

OpenSearch Description files: XML files that identify and describe a search engine.
- OpenSearch Query Syntax: describe where to retrieve the search results
OpenSearch RSS (in OpenSearch 1.0) or OpenSearch Response (in OpenSearch 1.1): format for providing open search results.
OpenSearch Aggregators: Sites that can display OpenSearch results.

OpenSearch Description Documents list search result responses for the given website/tool. Version 1.0 of the specification only allowed one response, in RSS format; however, version 1.1 provides support for multiple responses, which may be in any format. RSS and Atom are the only ones formally supported by OpenSearch aggregators, however other types, such as HTML are perfectly acceptable.
