In which case the problem becomes "doing mashups where data needs to have different metadata associated is impossible", so the requirement is "enable mashups to carry different metadata about bits of the content that are from different sources. A use case for this: There are mapping organisations and data producers and people who take photos, and each may place different policies. Being able to keep that policy information helps people with further mashups avoiding violating a policy. For example, if GreatMaps.com has a public domain policy on their maps, CoolFotos.org has a policy that you can use data other than images for non-commercial purposes, and Johan Ichikawa has a photo there of my brother's caf?, which he has licensed as "must pay money", then it would be reasonable for me to copy the map and put it in a brochure for the caf?, but not to copy the data and photo from CoolFotos. On the other hand, if I am producing a non-commercial guide to caf?s in Melbourne, I can add the map and the location of the cafe photo, but not the photo itself. Another use case: My wife wants to publish her papers online. She includes an abstract of each one in a page, but because they are under different copyright rules, she needs to clarify what the rules are. A harvester such as the Open Access project can actually collect and index some of them with no problem, but may not be allowed to index others. Meanwhile, a human finds it more useful to see the abstracts on a page than have to guess from a bunch of titles whether to look at each abstract. cheers Chaals -- Charles McCathieNevile Opera Software, Standards Group je parle fran?ais -- hablo espa?ol -- jeg l?rer norsk http://my.opera.com/chaals Try Opera: http://www.opera.com
