the bus is shared so if you have a separate object dbus is effectively
filtering on that object - its no different from setting up a manual
match rule to filter on a QueryID

yes - toolkits already integrate with dbus unless I misuderstood what
you mean?

toolkits can further abstract and avoid dbus'isms like libtracker but
they are not strictly necessary



You understood correctly. You mean to let apps use that interface directly.
I was asking if you intended to wrap that api in a toolkit  dependent client
(which you didn't).

yes true - we can add those

right we need to get all the *simple* requirements from apps so that the
initial searech interface is useful (if not all powerful). If it can
address 90%+ of needs then it will succeed.



Ok. My opinion is this:

Create a simple api for direct use. No live queries, just batch deliverance
and support for paging (much like the current spec on WasabiSearchSimple).
The question on whether to standardize on a simple query (non-xml, maybe
beagle-like syntax) language as well remains open.


When we have the simple interface in place, create a "live" (or "full")
interface to support live queries and what not. This includes a XML query
language. This interface is intended for toolkit bindings (think native
Client objects in QT/Gobject), but should be usable without these.
