Opensearch

From Arnout Engelen

[edit] The format

OpenSearch mainly consists of a small document describing how search results pages (and 'live suggestions') can be reached.

The actual search result may be presented in a number of ways, such as a HTML page, RSS or ATOM feed. HTML pages probably can't be easily aggregated (but can be showed side-by-side), this might be easier for RSS or ATOM.

[edit] Aggregation

There don't seem to be any opensearch aggregators available, apart from the a9 one and the one integrated into drupal.

I wanted a standalone one, so I created a simple implementation dubbed Apadua.

• http://opensearch.a9.com/
• http://drupal.org/project/opensearch_aggregator
• https://developer.berlios.de/projects/opensearch/ - another search aggregator, that doesn't support opensearch yet (but perhaps could be extended).
