What is this?

This wiki serves as a main repository of high level terminology used by our group to work with data sources.

How to use this Wiki

Like any other vocabularies. Just define new terms for each concept that you want to use in your data or for normalizations, and use it.

Knowing the Variable, its CATEGORY, MEASURE, and mathematical DOMAIN, just translate that into a description like so:

When you write new concept to this wiki, you can access its URL by:

import metawiki
metawiki.name2url('GH:wefindx/terms/Variable#CATEGORY-MEASURE-DOMAIN')

Take a look at the examples, of how these terms appear in pages like Age, Timestamp, ... Price.
