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)
