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 "Auto-discovery" to signal the presence of a search plugin link to the user and the link embedded in the header of HTML pages
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.
- Auto-discovery of an OpenSearch Description Document is available from both HTML and Atom or RSS feed documents via Link relations in the form of
<atom:link rel="search" ... />for Atom feeds[6] or<link rel="search" ... />for RSS feeds[6] and HTML documents.[7] - OpenSearch Description Document must be placed on a web server of the same domain.[8]
- OpenSearch Description Documents must be served with the
application/opensearchdescription+xmlInternet media type.[9]
