apt-listbugs filter package by ubuntu and upstream version

[Tim Webster]

I am working to integrate apt-listbugs with bugs.launchpad.net

As part of this integration work, I am interested in filtering
bugs.launchpat.net request by
ubuntu version and debian upstream version if any.

For example
Package: openoffice.org

ubuntu
Version: 1:3.0.1-9ubuntu3

debian upstream
Version: 1:3.0.1-9


I am aware of http://qa.ubuntuwire.com/bugs/rcbugs/
But I would like to retreive all the required information,
from bugs.launchpad.net and http://bugs.debian.org


Is there additional documentation on the available bugs.launchpad
fields. Or alternative the source code where I can extract this
information
