A nexus represents some historical event or state that can span both time and space.
If you think of histori.city as a geo-temporal version of Wikipedia, then a "page on Wikipedia" is roughly equivalent to a "nexus on histori.city".
The nexus is the atomic unit of information, and the entire histori.city 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.
- name: every nexus has a name, unique amongst all others.
- time: every nexus happened sometime. It can have a start time and an end time.
If the start and end times are the same, we say the nexus occurred at a particular instant in time.
If they are different, we say that the nexus spans a time range.
- location: every nexus happened somewhere. It could be a single point (latitude/longitude), for example the Battle of Waterloo,
or it could be a shape (a sequence of latitude/longitude points), for example the extent of the Roman Empire under Trajan.
- tags: describes concepts that relate to this nexus. Learn more about tags.
- commentary: free-form text, with Markdown support: the written word lives on!
When viewing the histori.city 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:
You will be able to create new nexuses, and designate them as public or private.
You will be able to edit any nexus that is visible to you, and other users will be able to edit any nexus that you have made visible to them.
All nexuses will be versioned. Every edit creates a new version (just like Wikipedia), so nothing is ever lost.
Different people can have different versions of the same nexus.
We will exercise some editorial control over which version of a nexus is designated as the authoritative public version.
The default view for anonymous users will be the authoritative public nexuses.
When making a designation of whether a nexus should be considered authoritative,
we will embrace transparency, impartiality, and a clear and shared understanding of the rules and standards being applied.
Regardless of our choice of the authoritative version of any particular nexus, you will be able to set a list of preferred authors
(and also blocked authors) to customize your own view of histori.city.
