Hi all, I agree Michael, and I had put a note to this effect on the original google doc. We deal with the same issue all the time, and ideally we'd be able to automate the display of the provenance chain if such a thing were specified well enough.

I will ponder about your edit suggestion of your first bullet point. I am not sure at the moment if it would have wider implications. You are right that the use cases were written by the groups themselves. I do not know how to improve the use cases without rewriting them, which might not be agreeable to all parties involved. C'est la vie. The role of Data Catalogs should then be discussed during out next conf call. Thanks for highlighting that this might be unclear to readers.
