: Tracker is a freedesktop project (with GNOME roots) included in the maemo platform for the first time in maemo5. In fremantle it is a simple index engine with support for basic metadata. For harmattan Tracker takes a great leap forward becoming a central storage for *user information*. The important data for the user (contacts, messages, multimedia, ...) will not only be stored in an application independent way, but also in a "linkable" format. This enables a new user experience: it makes it possible to integrate contacts everywhere, mix IM/email/twitter history of a contact, and so on.
+
: QtTracker is a Qt Object RDF Mapper with Tracker backend. It supplements Soprano, offering intuitive resource access, property traversal, sophisticated query building, live update handling, simple client-side transactions, powerful caching, and other convenience features at the top convenience layer, but also lower tier access supplying direct sparql etc. QtTracker is native C++, and integrates extensively with Qt.
-
 
+
: The upcoming release is the first public LGPL release of QtTracker, and an introduction is given into why, when and how QtTracker should be used. After that a basic example application presenting idiomatic usage of core features will be discussed.
-
In this presentation, Application developers can see how data is linked and obtained from Tracker to enrich their applications; platform contributors can learn how to integrate new information sources.
