I have posted
the message below freedesktop.org's xdg list. Your comments there are
Tracker integration in Evolution is something that has been wanted for a
long time (see Benjamin Otte's post from 2009 here
<http://blogs.gnome.org/otte/2009/07/23/semantic-desktop/>). My point is
that it probably will never happen because Evolution developers does not
trust the performance characteristics of a foreign, all-desktop database
like Tracker (am I right?). What I propose then is that instead of
expecting Evolution to come to the semantic desktop, the semantic
desktop should come to Evolution; instead of Evolution using Tracker as
its back-end, EDS should be exposed to Tracker in a format that Tracker
understands (namely RDF).
My proposal to xdg is a stab at an interface for accomplishing such an
exposure. Basically, EDS would be exported as a D-Bus object with
similar semantics to a 'graph' in Tracker.
Can you imagine yourselves (the Evolution team) maintaining a component
implementing such an interface in Evolution?

Subject: [RFC] Metadata access and storage
Date: Tue, 06 Sep 2011 00:44:42 +0200
From: Anders Feder <lists.and...@feder.dk>
I would like to propose a new standards activity: metadata access and
The mission is as follows: "Define a single, unified interface for
access to all metadata on the desktop. Then extend it to support
insertion (storage) of metadata too."
There has been at least one previous effort of this kind that I know of
(Xesam), but most parts of it seems to have been either consumed by
other projects (NEPOMUK), or abandoned completely (notably the query
language). In any case, the state of affairs appears to be that there is
no standard interface for accessing metadata: Evolution, Nautilus, etc.
all still exist as separate silos - not as a unified whole which can be
queried through a single interface. - It's 2011, and I /still/ have to
manually copy contact information from Empathy to Thunderbird.
Benjamin Otte gave a pretty good review of the situation (as far as
GNOME goes) here: http://blogs.gnome.org/otte/2009/07/23/semantic-desktop/
As always, all options are open, but my own tentative proposal -- titled
Semantk -- will give you an idea of what I have in mind:
How would /you/ solve this problem?
