What is a classification version?
A classification version is a list of mutually exclusive categories representing the version-specific values of the classification variable.
A classification version has a certain normative status and is valid for a given period of time.
A new version of a classification differs in essential ways from the previous version. Essential changes are changes that alter the borders between categories, i.e. a statistical object/unit may belong to different categories in the new and the older version. Border changes may be caused by creating or deleting categories, or moving a part of a category to another. The addition of case law, changes in explanatory notes or in the titles do not lead to a new version
