Hi Carlos, Thanks a lot for the links! I've been collecting a list at https://www.w3.org/2013/dwbp/wiki/Data_quality_notes#Links.2C_related_work I've added your ones that were not there (all but one!) We should certainly study all this at one point. For the moment however we'd like to give it a try to define quality by our own use cases and best practices. Especially for defining what is in scope or not. There is indeed a lot of related work, mostly academic, and this could end in trying to tackle many things, some perhaps less important than others. Cheers, Antoine PS: @Carlos sorry I won't have time to answer on the other (BP/vocabulary) thread very soon...
