OpenSearch has two meanings, because the preferred way to name anything
|
|
|
|
when it comes to computers is to make it as confusing as possible:
|
|
|
|
|
|
|
|
- OpenSearch was a specification for an XML description of search
|
|
|
|
engines which was particularly used to allow auto-discovery of search
|
|
|
|
engines by web browsers before it got unnecessarily replaced by
|
|
|
|
Chrome's WebExtensions.
|
|
|
|
- OpenSearch is a search engine software licensed under Apache 2.0.
|
|
|
|
|
|
|
|
The OpenSearch specification used to be hosted by an Amazon subsidiary
|
|
|
|
called A9, and you can still see a trace of it in the XML namespace URL:
|
|
|
|
`http://a9.com/-/spec/opensearch/1.1/`. It then has been hosted on
|
|
|
|
opensearch.org before the domain name got stolen by the search engine
|
|
|
|
software.
|
|
|
|
|
|
|
|
- [GitHub repo][github] linked on the Wikipedia page
|
|
|
|
with a backup of the OpenSearch site
|
|
|
|
- [Latest archived version at OpenSearch][opensearch-spec]
|
|
|
|
- [Latest archived version at A9][a9]
|
|
|
|
- [Latest archived version of OpenSearch][opensearch]
|
|
|
|
(the spec was moved to GitHub before the site died)
|
|
|
|
|
|
|
|
I discovered this specification by trying to find out why the official
|
|
|
|
DuckDuckGo Lite and HTML search engines on the SeaMonkey add-ons site
|
|
|
|
were not working properly. If you have gone through other articles on
|
|
|
|
this wiki you probably already know that if there's an XML somewhere,
|
|
|
|
I ought to find or create an XSD for it.
|
|
|
|
|
|
|
|
A developer at Microsoft seemed to have the same mindset as me in 2008
|
|
|
|
and [announced an XSD][xsd-blog] on his blog. The linked schema in the
|
|
|
|
blog article points to [a file on Windows Live SkyDrive][xsd-skydrive],
|
|
|
|
and while the file's listing has been archived, the file itself has not,
|
|
|
|
so we are back to square one. So I went ahead and just wrote my own
|
|
|
|
XSDs for OpenSearch, including all of its extensions.
|
|
|
|
|
|
|
|
## XSD
|
|
|
|
|
|
|
|
* [OpenSearch 1.1 Draft 6](./opensearch.xsd)
|

|
|
* [OpenSearch Geo Extension 1.0 Draft 2](./geo.xsd)

|
|
|
|

## OpenSearch descriptions
|
|
|
|
|
|
|
|
I wrote some OpenSearch descriptions myself and am hosting them on this
|
|
|
|
site. If you are using a browser that supports OpenSearch description
|
|
|
|
autodiscovery, you should be able to just click a button near your
|
|
|
|
browser's search features to pick between the available search engines.
|
|
|
|
Some browsers might even be able to automatically update the files if I
|
|
|
|
ever need to change them. If your browser doesn't support
|
|
|
|
autodiscovery, well you can just grab the XML files yourself here:
|
|
|
|
|
|
|
|
* [DuckDuckGo Lite](./ddglite.xml)
|
|
|
|
* [DuckDuckGo HTML](./ddghtml.xml)
|

|
|
|
* [Mamont (Russian)](./mamont.xml) (FTP search engine)
|
|
|
|
* [Mamont (English)](./mamont-int.xml) (FTP search engine)
|
2021-10-24 19:10:55 +00:00
|
|
|
* [Veronica-2](./veronica2.xml) (Gopher search engine, proxied over HTTP)
|
2021-10-24 19:28:02 +00:00
|
|
|
* [wttr.in](./wttr.xml) (weather forecast)
|
2023-11-26 13:28:09 +00:00
|
|
|
* [Météociel](./meteociel.xml) (weather forecasts from a French association)
|
2021-10-24 21:34:50 +00:00
|
|
|
* [dict.org](./dict.xml) (dictionary)
|
2021-10-24 22:02:01 +00:00
|
|
|
* [Internet Archive](./archive.xml)

## To-do
|
|
|
|
|
|
|
|
- Try to retrieve all the search engines that were known to A9 and see
|
|
|
|
if they are still working, or maybe just document their existence
|
|
|
|
<http://web.archive.org/web/20090131091222/http://a9.com/-/opensearch/searches.jsp>
|
|
|
|
|
|
|
|
- Look around the search engine directories that were known to OpenSearch.org
|
|
|
|
<http://web.archive.org/web/20120301211959/http://www.opensearch.org/Community/OpenSearch_search_engine_directories>
|
|
|
|
|
|
|
|
- Learn more about the poorly documented Mozilla extensions to
|
|
|
|
OpenSearch descriptions such as `Param` and `SearchForm`
