Unit


Definition: Unit
A unit can only be an object of a relation. 

As a result a Unit is a special kind of object, it can not be a subject .

Example

A computer

In a computer the Unit is a bit value. This is the smallest Unit with which current computers can work. 

XML

In XML the Unit is a UNICODE character. This is the smallest Unit with which XML aware applications can work (e.g. parsers, translators, ...)

Note:
In XML you can have external entities which are not based on UNICODE, but as the name implies these are external to XML.

Current Mathematics

Current Mathematics works with 2 Units. The numbers 0 and 1. All other mathematic numbers (which are actually expressions) can be written as a sequence of functions on these numbers.

Compositional Mathematics

In Compositional Mathematics there is only 1 Unit. Everything else is a composition.

A complete description of Compositional mathematics will be available in the forthcoming book "Compositions" by Koen Van Exem.
