event logging framework

 Zeitgeist is a service which logs the user's activities and events
 (files opened, websites visited,
 conversations held with other people, etc.)
 and makes the relevant information available to other applications.
 .
 It serves as a comprehensive activity log
 and also makes it possible to determine relationships
 between items based on usage patterns.
 .
 This package depends on the Zeitgeist engine
 and a set of packages (such as data providers)
 commonly used together with it,
 and additionally provides the RDF ontologies used with Zeitgeist.
