All about the search infrastructure of Akonadi.

== Concept ==

Concept of the Akonadi search infrastructure:

[[File:Akonadi-search-infrastructure 20090723.png]]

== Query Language ==

Options:
* SPARQL: de-facto standard by now (used by Nepomuk and Tracker), but way too complex for automatic query transformations.
* XESAM (?)


== Search Backends ==

Requirements:
* fast enough
* cross-platform
* persistent/live search with change notifications

=== Possible Backends ===

* Nepomuk with Sesame2 or Virtuoso
* Tracker (?)
* XESAM (?)

=== Delegation to Resources ===

* Requires query transformation
* Requires management for live searches
* Requires the ability to report search results (needs protocol extension) [done by now]


== Virtual Collections ==

Virtual collections are used to report results, for details see [[PIM/Akonadi/VirtualCollections]].
