Evaluating DocBook and DITA

["Eric Johnson" <EMJOHNSO@progress.com>]

My company is in the middle of deciding what tools to consolidate on. We
currently have one fairly large project using DocBook and another small
project using DITA.
I'm trying to find some resources that would lend some expert opinions
on how to determine which is a better solution for our company. Any
pointers, and opinions, would be welcomed.
Thanks,
Eric
