apt package channel / python-apt

["Frédéric PICA" <frederic.pica@gmail.com>]

Greets,

I have some interrogations about apt :
I want to develop a centralized system holding what packages operations happened on a remote debian system (in a database).
I'm using the DPkg::Pre-Install-Pkgs apt option to get information about what packages are installed/removed/updated but I need also to know from wich channel the package come (channel + url).
I have took a look at python-apt but I didn't find a good documentation :(, the same for libapt... so I've got some troubles to use it.
Is there a tool that can give me this information from the name and version of a packet ?

Thanks for your help,
Frédéric PICA
