Wikipedia URLs hover on the edge of what is possible but look close and you see temporal stability is poor and often the ontological properties are wrong. (E.g. you can’t say that a Boeing 777 has a certain weight or length because there are various variants of it that don’t have individual Wikipedia pages, same is true for fighter jets, car models, etc.)
When you have a million entities you are often better off using randomly generate UUID’s. People won’t know what they mean but at least sound reasoning would be possible over the domain.
I still don't understand what some of our stuff does and it has common names that are descriptive, because documentation sucks. They could be called Widget and Whoozit for all I care, as long as there is documentation!
