[Nepomuk] Adding Nepomuk integration into Basket Note Pads

[Sebastian Trüg]

Let's bring this discussion to the mailing list. A quick recap:

Amir wants Nepomuk support in Basket to be able to search notes.
He started by adding tags to resources that he created for the notes
since that is what the tutorial does.
But his problem was with opening the tagged notes which would be done by
the browser (nepomuk:/ KIO slave).
Thus, I proposed to start off by saving the note in a file and tagging
and annotating that file.
A next step would mean to introduce a system similar to what we have for
mimetypes: applications should be able to register for specific RDF
types they can handle.
I also brought Laura into the discussion since she faces similar
problems with SemNotes. Also it would make sense to either merge the
tools or make their data compatible through Nepomuk.

Then Akonadi was mentioned and the always problematic question arose:
should we store the data in Nepomuk or Akonadi. Well, I am all for
Nepomuk since we would duplicate everything there anyway to be able to
search for it.

And this is where we are now:

Akonadi does not do syncing AFAIK. Nepomuk sync support is developed by
Vishesh at the moment. Vishesh, how far away are we from syncing for
example a set of notes to another computer?

the KRunner only knows KIO - thus, it can open files and opens the rest
through KIO. In the case of Nepomuk resources this means the browser
(preferably Konqueror) with the nepomuk:/ KIO slave. The latter provides
an HTML page with the properties of the resources. Lately we also
redirect most of the resources to queries listing the related
resources/files.
