NOARK is the National Archives standard for how documents are to be registered, versioned, tracked and ultimately disposed of in public bodies. The current version is Noark 5. The requirements are about a document remaining retrievable with its history intact: who created it, what changed, when it was archived, and if deleted - that the deletion itself is documented. Municipally owned grid companies and other publicly affiliated energy companies are covered, and for them NOARK is not a recommendation but a requirement at inspection.
