use Get method on the metadata interface
<interface name="org.freedesktop.Tracker.Metadata">
<!-- Retrieves an array of metadata values for the specified
array of
metadata keys for a service and id pair-->
<method name="Get">
<arg type="s" name="service" direction="in" />
<arg type="s" name="id" direction="in" />
<arg type="as" name="keys" direction="in" />
<arg type="as" name="values" direction="out" />
</method>
see tracker-introspect.xml for description of all methods
I dont know enough python to give you python examples
but call Get ("Files", "/home/jamie/filename", ["File:Size",
"File:Mime"], output)
