Re: [Tracker] [Use case] Distribution Packages Management

[Ivan Frade <ivan frade gmail com>]

hi all!

 Tracker likes information that can be linked with other information, and this link must be useful for the user!  I don't see the raw package database giving any new interesting new connection... and usually package management software has strong performance requirements and complex algorythms to run. 

 Basically i wouldn't use tracker for that unless we find a nice use case for the user (and not just an engineering convenience). But hey, this is open source! :)

Regards,

Ivan

The application that runs PackageKit's dialogs doesn't run as root, it's
that code that should do the queries directly to tracker-store, not by
first going to packagekitd.

A difficulty that I see is that the user must have read access to each
package system's database, for his miner to successfully read it and
pump it into RDF. But for example apt-cache can read from the db as
user, so apt and dpkg are good, I guess. I think YUM & RPM also allows
this.

I remember that among the questions at FOSDEM was that app developers
want a query interface to packagekit, to make queries against the
metadata of the packages.

That could indeed be implemented with tracker-store as RDF store and
SPARQL service.

But again, do it clientside in packagekit's libraries. No need to go
through root-process packagekitd for this.
