worldwide consensus on tagging. This will never happen as long as the tags
are so subjective. Check out the thread on the definitions of
cafe/restaurant/fast_food for a wonderful case of what happens if the input
side rules the project. You have heard of ROM? Ever heard of WOM? A large
part of the IT budget of large companies is spent on "understanding" the
data they already have. Missing or incorrect documentation, misuse of
fields (overloading), no data quality control... I spend my life trying to
save them money. Unfortunately every day they are still creating more of
tomorrow's "legacy."

I think we don't need IBM Watson, we just need a database of semantically
organised tags. A database which has categories like  "a place where you
can buy food for money" which has restaurants, fast foods and convenience
stores in it. Geography has to plays a role in it. Maybe in Japan a
convenience store doesn't have food in it.

Then a data consumer tells its renderer "render this category with a big
fork and knife" and that's all there is to it.
