Mapping The Corporate Open Source World?

jukal asks: "I am building a contact database about open source activities and their contacts in large companies. It will be a kind of 'mindmap' positioning each of the big players, listing their key characteristics, their publically stated views on Open Source, and possible connections between the activities of the companies. Could you provide me with a helping hand to get started. Yes, I am doing this for the purposes of Openchallenge but I believe many others would benefit as well. I would like to map the open source world from the 'corporate viewing point' :) Post the details - or anything you got - here, or directly to me [/. profile] And as there will anyway be someone saying 'Go Google It Yourself' - If you think it's Google-able, give it a shot. If this has been already done, then that would be excellent!"
