In a report sponsored by ContentGuard, the authors discuss the use of digital rights in content management systems. Some good diagrams illustrate fairly clearly the mechanisms involved. No mention of Open Digital Rights Language (ODRL), the major competitor to ContentGuard's XrML. The document spends a lot of time talking not merely about the sale of online content, but also the exchange of proprietary documents within an organization (which is also the marketing Microsoft used to promote its Rights Management Server, mentioned here a few months ago (click '[Research]', select 'Digital Rights Management' and you'll find the article from February in the resulting search)). As I was reading this item I found myself wondering whether the mechanism used to protect corporate secrets ought to be the same as that used to protect a content vendor's copyright. It really does seem like overkill. PDF (which wouldn't let me cut and paste, claiming that my computer is out of memory).
