All about the search infrastructure of Akonadi.

Concept

Concept of the Akonadi search infrastructure:

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.
