The short answer is, as Jim noted, this is not what DSpace is about. The slightly longer answer is, watermarked images and other media can easily be managed within a DSpace; in fact, with an appropriate watermarking technology, the identifier used for the object in the DSpace could be used as the watermark's payload. Watermarks have been able to do this for more than ten years, and this basic capability has always been available to DSpace adopters (although I don't know of anyone who has actually done it). The compliance aspect of Henrik's question is a totally different matter. Except for the very, very limited case where "usage" means archiving and access within other DSpaces, the general problem of compliance checking is WAY out of scope for DSpace. And in the case of usage within other DSpaces, watermarks are not required. The longer-still answer is, this sort of in situ compliance checking has been on the DRM "Holy Grail" list for more than ten years, and scale makes it an almost intractable problem. The first to attempt it was Digimarc, with limited success, due to scale and visibility of targets. The problem is made slightly more tractable by leveraging the scale of Google, but that still only covers a subset of the placement rights that would be licensed. But even holy Google is only a minor deity, and does not see everything. In other words, you really DO NOT want to attempt this yourself. And if your boss or client desperately wants you to, hire out the spidering and archive the watermarked media as I suggested. And remember, "I told you so!" ;) John PS: This is my personal opinion as one of the old-timers in world of "DRM" and not that of HP... ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
