Classification levels

[cpotter]

The field/metadata "Importance" contains some classification values (Personal data, Confidential, ...) and importance values (Normal, High, ...) all mixed. The need of a new field "Classification" seems to be important to separate both meaning (Importance and Classification/Dissemination). Here are the proposed values :

Diffusion	Value	Rules
	Civilian
	Not Classified (default)
	C1 - Internal Use	B
	C2 - Restricted Distribution
	C3 – Secret / Confidential	A
	Military (FR)
	Restricted Distribution
	Secret-Defense	A
	Top Secret-Defense	A

The NATO and TLP (CISA - Cybersecurity & Infrastructure Security Agency) classifications will be added to these lists if necessary.
