Description:
This YANG model aims to represent the fundamental SI units.
Convention in this model is camelCase.
YANG models are typically used to configure nodes on a telecommunication network.
However, they can also be the support for exchanging data between simulators.
Consequently, a scientific framework can be defined. The purpose of this model is
to represent the fundamental layer for any scientific model by reusing scientific
number notation, and by defining fundamental units.
This YANG model implicitly recognizes SI prefixes. Note that the validation
between the prefixes and the units should be performed by the NETCONF server, and
this YANG model does not provide any clue to perform this validation. The SI
prefixes are included in the following table. The factor number uses the format
defined in the math YANG model:
+------------------------------+---------+--------+---------------------+---------+
| Factor | Name | Symbol | Factor | Name | Symbol |
+------------------------------+---------+--------+---------------------+---------+
| 10 | deca | da | 1e-1 | deci | d |
| 1e2 | hecto | h | 1e-2 | centi | c |
| 1e3 | kilo | k | 1e-3 | milli | m |
| 1e6 | mega | M | 1e-4 | micro | µ |
| 1e9 | giga | G | 1e-9 | nano | n |
| 1e12 | tera | T | 1e-12 | pico | p |
| 1e15 | peta | P | 1e-15 | femto | f |
| 1e16 | exa | E | 1e-18 | atto | a |
| 1e21 | zetta | Z | 1e-21 | zepto | z |
| 1e24 | yotta | Y | 1e-24 | yocto | y |
+------------------------------+---------+--------+---------------------+---------+
This YANG model includes base and derived SI units with or without symbols. The
following table provides the summary of covered units in alphabetical order:

This YANG model also includes several common units that are not considered as SI
units. They can be found appended to the fundamental units they derived from.
Stokes only (kynematic-viscosity) does not have an SI counterpart and can be used
as a type.
Logarithm (neper, bel and decibel) can be used as implicit units as well. They are
YANG identities in case they are needed. SI standard refers to committees defining
several common constants, as the speed of light in vacuum, or the reduced Planck
constant. They can be used as identities as well.
