Now let us see how a classification for sex could be documented in a classification management system – obviously you would not go to this amount of documentation unless the classification had a high amount of stability and/or was the result of a lot of preparatory work and/or international/national agreements.

abbreviation of its title.

Classification version

Identifier: A classification version is identified by a unique identifier, which may typically

be an abbreviation of its title. It is often distinguished from other versions of the same

classification by reference to a revision number or to the year of the version's coming into

force.

Ex .: 2946101

Title: A classification version has a title as provided by the owner or maintenance unit.

version.

Introduction: The introduction provides a detailed description of the classification version,

the background for its creation, the classification variable and objects/units classified,

classification rules etc.

Ex:

Maintenance unit: The unit or group of persons within the organisation who are responsible

for the classification version, i.e. for maintaining, updating and changing it.

Indicates the languages available, whether the version is completely or partially translated,

and which part is available in which language.

Ex: Norwegian bokmål, Norwegian nynorsk, English

Floating : If a classification version is updated often, it can be marked as a floating

classification version. In a floating classification version a validity period should be defined

for all items which will allow the display of the item structure and content at different points

of time.

Ex: No

Updates possible: Indicates whether or not updates are allowed within the

classification version, i.e. without leading to a new version. Such updates will usually be

changes, which add items to the structure and/or revalidates/invalidates classification items

but which do not alter the borders within the structure of the classification versions.

Ex: No

Changes from previous version: Summary description of changes which have occurred

from the previous classification version to the actual version.

Ex: Not relevant

Updates: Summary description of changes which have occurred within the classification

version.

Ex: Not relevant

Copyright: Classification versions may have restricted copyrights. Such versions

might be excluded from downloading and should be displayed in official publications (e.g.

WEB) indicating the copyright owner.

or disseminated (e.g. on the Web).

Ex: No

Classification: A classification version is a version of one specific classification.

Ex.: Classification codes of sex

Ex: Not relevant

Successor version : The classification version immediately following the actual version.

Ex: Not relevant

Derived from: A classification version can be derived from one of the classification versions

of another classification. The derived version can either inherit the structure of the

classification version from which it is derived, usually adding more detail, or use a large part

of the items of the classification version from which it is derived and rearrange them in a

different structure. Indicates the classification version from which the actual version is

derived.

Ex: Not relevant

Levels : The structure of a classification version is defined by its levels (classification level).

Ex: Level 1 Sex

Items : A classification version is composed of categories structured in one or more levels.

Each category is represented by a classification item, which defines the content and the

borders of the category.

Ex: Not relevant

Correspondence tables: A classification version may be linked to other classification

versions or classification variants through correspondence tables.

Classification indexes: A classification version can be associated with one or a number of

indexes in which index entries are linked to the appropriate classification item.

belongs to a floating classification version and is no longer valid.

Ex:

Past events : The past events describe a change (or a number of changes) that have created

the item e.g. from one or several predecessor items (see Item Change). This allows tracing of

the history of an item including changes such as new code, fusion or splitting.

Ex:

Future events : The future events describe a change (or a number of changes) related to an

invalid item. These changes may e.g. have turned the now invalid item into one or several

successor items (see Item Change). This allows the possibility to follow successors of the

item in the future.
