Re: Data Q&G vocabulary - report and questions for F2F

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...
