A nexus represents some historical event or state that can span both time and space. If you think of as a geo-temporal version of Wikipedia, then a "page on Wikipedia" is roughly equivalent to a "nexus on". The nexus is the atomic unit of information, and the entire system is, in one sense, nothing more than the totality of the nexuses that comprise it.

A nexus is known by a name, has a well-defined location in time and space, and may have some tags and commentary attached. The attributes of a nexus are described in more detail below.

When viewing the site today, you are seeing only the data we have auto-imported from Wikipedia using our special open source tools.

We will soon introduce a new version that allows end users to contribute historical data. Then we can have some real fun:
