Yes, possibly once I've gotten my head around dbus and tracker. ;) Until then I resorted to start a dbus session and tracker via a small shell script: ---8<--- #!/bin/sh eval `dbus-launch --sh-syntax --config-file=/usr/local/netatalk/etc/dbus-session.conf` echo "D-Bus per-session daemon address is: $DBUS_SESSION_BUS_ADDRESS" nohup /usr/lib/tracker/trackerd & ---8<--- I've put a <listen> directive with a TCP address (127.0.0.1:12345) in the dbus-session.conf so DBUS_SESSION_BUS_ADDRESS is a known value which I can export to my a shell where I play with tracker-search and putenv() to the environment of the relevant Netatalk process (afpd) which will call tracker-sparql C API stuff. Btw, we're now facing the interesting problem of translating Apple's Spotlight query syntax to SPARQL. An example for a more complex Spotlight query: ((true) && (((kMDItemResolutionHeightDPI < 72) && (_kMDItemGroupId = 13) && InRange(kMDItemContentModificationDate,360453600.000000,363132000.000000)))) && ((* = "pic*"cdw || kMDItemTextContent = "pic*"cdw)) That's a search for a picture (_kMDItemGroupId 13) with a string "pic" a the beginning of any metadata attribute or filename, changed within the last 30 days (kMDItemContentModificationDate) and a resolution smaller then 72 dpi. We're looking for interested persons or companies who might be interested in doing paid work on this. In case you're interested please contact me off-list.
