Here is a counter example to your test. If we view an entire nation as one entity, especially considering the perspective of other nations in terms of diplomatic relationships, the nation would satisfy all requirements in your test. However, I don’t think most people believe that a nation has continuous consciousness which outlives all of its citizens for hundreds or even thousands of years. This argument can be applied to any large organization or a group of people.

It’s quite common for a DOI to be assigned to a paper after it’s accepted during camera ready. However, the DOI won’t work until the conference or journal version is published on the official website (ACM in this case). The version you’re viewing now is simply a preprint directly from the authors.

Can this be solved by storing a timestamp of the record along with precise GPS coordinates? Could we then utilize some database to compute the drift from then and now?

A related question: what is the state in term of supporting the SQL standard among the popular RDBMS? It seems that almost all database engines use their own custom syntax.
