Yes, but it's not a commercial product, at least not at this time. I talked with Chris Feola about that point just last night. I'm a little groggy from the trip back from Dallas but here's a summary. Belo has created its own multimedia content management system using XML when appropriate in an object data approach. Parts of the system run on RedHat Linux.
Content is separate from presentation, etc.
This is very new stuff. I don't think the system is entirely rolled out within the Belo properties.
