Maemo 5 uses Tracker 0.6 to consolidate most of metadata of files indexed already. Harmattan (Maemo 6) is extensively using current Tracker master branch and utilizing SparQL language as its query mechanism. Tracker master (0.7.x) and Tracker 0.6 use different storage backend and query mechanisms, it is quite a big difference, and it seems most of non-file based data is going to be indexed as well, according to the ontologies being developed.
You can find current maemo-specific modifications of Tracker at http://maemo.gitorious.org/tracker/, these are synced well with Tracker master at gnome.org. If you want to develop something useful for Maemo 5 and 6 indexing, it would logically be good to at least learn what is happening in this area already and co-operate with existing code running on the device. -- / Alexander Bokovoy _______________________________________________ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
