Is Beagle a GNOME technology?
Beagle is designed to be desktop independent. Beagle does require the GLib library for the daemon, and may require other GNOME libraries for GNOME-specific backends (such as the Evolution backends), but those dependencies are optional, and do not stop it from working on KDE or other desktop environments. Beagle supports many KDE-specific backends. Check the Supported Filetypes page to see a list. The included user interface is a GNOME application, but it too is an optional build. There are many other search interfaces that are shipped separately. KDE interfaces include Kerry and yaBi.
