Re: [Tracker] tracker 1.2.4



Hi All
As a non coding user type of follower of Tracker, this is very similar to how i would like to organise my thousands of images. Hence text/strings attributes stored within( metadata )image files.
Cheers JohnB

Hallo Martin,

Tracker uses W3C standards for RDF ontologies using Nepomuk with
SPARQL to query and update the data.
Thanks Martyn for that bit of information!
I just learned from it, that Nepomuk is a common ground in KDE and GNOME.
Am I right?
That depends a bit.

How close is the relation?
Tracker technically uses Nepomuk + extensions to fill the gaps we need
filling, so yes it does use the standard, but not the library or source
works from the KDE folks.

 From what I've heard lately, KDE is moving away from Nepomuk, so it was
common but perhaps not now?

As for libnepomuk*, I have no idea, but we're not using it.

Is there a chance of, e.g., dolphin using the same RDF-store as tracker?
Well, tracker is an RDF store. Perhaps you mean "using the Tracker RDF
store" ?

Would I break tracker if I tried it out?
Try away, but it's unclear to me what you think you would be breaking
here. If you have indexed content in Tracker and you change the
ontologies installed in to /usr/share/tracker/ontologies/ then the next
restart of tracker-store might spit errors out at you ;)

well, my first attempt lead to reindexing my files with baloo
I diden't want that because I would really like to stick with GNOME.
dolphin can't (at least on first sight) use the tracker store.
I was hoping I could keep tracker as backend and use dolphin to browse
and search and (most important for me) to edit tags.

even in this very short time I started to really like dolphin.

I just browsed through the Nepomuk and semanticdesktop.org sites. There
is a lot of good ideas and promising tools.
The "DropBox" for one; I'd really like to try that one.

What do you think?
I've not looked into it personally.

btw.: I used to do some research in a semantic-web project (called SWAP
- you can still find it online - http://www.aifb.kit.edu/web/SWAP) years
ago myself ...
What's your aim here, may I ask?

of course you may :-)

I very much like the idea of a semantic desktop.

Having all your data dynamically grouped or structured by different
(combineable) criteria, e.g., (self attached or automatically extracted)
tags, timeline, type, location, etc. is really the way I would like to
organise myself.

unfortunately the (as of today) useable tools, that go in that direction
are still quite far away from this vision.

SWAP is just one of so many academic projects ...
by chance I had a tiny part in this one ;-)

Another project I worked with, used to calculate a semantic distance
between documents and graphically arranged them according to this
distance. So if you selected a document, the "closest relatives" based
on a changeable set of criteria were grouped near it, others further
away in a hyperbolic tree http://en.wikipedia.org/wiki/Hyperbolic_tree.
This one was an internal project at Dresdner Bank, so it is not
available to the public.

So that was a little trip on my motivation behind this discussion ...

greets
martin
