Ian, Using licensing to ensure the data providers URIs are always preserved delivers low cost and implicit attribution. This is what I believe CC-BY-SA delivers. There is nothing wrong with granular attribution if compliance is low cost. Personally, I think we are on the verge of an "Attribution Economy", and said economy will encourage contributions from a plethora of high quality data providers (esp. from the tradition media realm). Anyway, each data set provider should pick the license that works for them :-) > > A group of us have submitted a tutorial on these issues for ISWC 2009, > hopefully it will get accepted because this is a really important area > of Linked Data that is poorly understood. > > > > 2.
