h1. Code Entity

A code is a common [[Thesaurus#Entity|entity]] that regroups [[Thesaurus#Entity|entites]] having following fields :

* a translatable [[Thesaurus#Code (Field)|code field]]

* a translatable description

Typical codes are "Type of...".

A code has two aspects :

* the definition of the code (the code itself)

* the list of values that can be selected in digest

The definition gives the meaning of the code, and says what it's used for. "Type of invoice" is a code, as well as "Invoice status".

The code has a type (which obsiously are codes too) : 

* System :

**user cannot modify the code except for its description

**user cannot add or remove values, neither modify an existing value except its description

* System/User : 

**user cannot modify the code except for its description

**user can add and remove values or modify existing values

* User : user created the code

**user can delete or modify the code

**user can add and remove values or modify existing values

Each value also has a type :

* System : user cannot modify the value, except its description

* User : user can modify the value

Accessible by a [[Thesaurus#Code (Field)|code field]]
