How was division 91, cultural activities, restructured?

Division 91, libraries, archives, museums and other cultural activities, was completely restructured in NACE Rev. 2.1. Paragraph 196 states that the division was split into four new groups: group 91.1, library and archive activities; group 91.2, museums, collections, historical sites and monuments activities; group 91.3, conservation, restoration and other support activities for cultural heritage; and group 91.4, botanical and zoological garden and nature reserve activities, with various classes therein. The restructuring does not determine a code for a specific reader.

What does the restructuring separate?

The restructuring separates four kinds of cultural activity that the old division held together. Library and archive activities form the first group. Museums, collections, historical sites and monuments form the second group. Conservation, restoration and other support activities for cultural heritage form the third group. Botanical and zoological gardens and nature reserves form the fourth group. The titles state the dividing lines in heading form, and the explanatory notes for the groups and classes state the contents in full. Section 4 does not name the classes inside the groups, and it states only that there are various classes therein. This guide does not invent class titles or numbers, and the detailed structure in Part 2 lists the classes.

The separation of conservation and restoration into its own group, and the separation of gardens and nature reserves into their own group, are the two most visible changes in the restructuring. Conservation and restoration work, previously held inside the general cultural division, is now grouped as support for cultural heritage, apart from the library, archive and museum work it supports. Gardens and nature reserves, previously held with the other cultural activities, are now grouped as a distinct kind of activity, with a title that names both botanical and zoological gardens and nature reserves. The grouping follows the character of the activity, and the notes state the boundaries, including the treatment of conservation work carried on inside a museum, where the notes for the groups concerned govern in general terms.

How does the restructuring relate to the notes for neighbouring classes?

The notes for the neighbouring divisions state boundaries that must be read with the division 91 notes. The note for class 63.10, for example, excludes electronic storage of archival material for access by the general public to class 91.12, which shows that digital archive work sits in division 91 even where the technology resembles computing infrastructure work. The note for the division 91 groups, in turn, excludes storage of data files and digitisation of files to class 63.10 where the work is data processing rather than archival activity. The two notes, read together, draw the boundary between archival activity and computing infrastructure activity, and neither note alone draws it completely.

The example is a reminder that a restructuring of one division cannot be read in isolation. The manual is a single classification, and the notes for classes in other divisions state exclusions that point into the restructured division, and exclusions in the restructured division that point out to other divisions. A reader who reads only the division 91 notes will miss the inbound exclusions from other divisions, and a reader who reads only the inbound exclusions will miss the content of the division itself. Both sets of notes must be read, together with the correspondence table, before an activity is placed in the division in general terms.

How is the restructuring shown?

| New group | Title in the manual |

|---|---|

| 91.1 | Library and archive activities |

| 91.2 | Museums, collections, historical sites and monuments activities |

| 91.3 | Conservation, restoration and other support activities for cultural heritage |

| 91.4 | Botanical and zoological garden and nature reserve activities |

The table follows paragraph 196. It lists the four groups and their titles, and it does not list classes, because paragraph 196 does not name the classes. The detailed structure lists the classes in each group, and the explanatory notes state their contents. The table in this guide is a summary of the manual summary, and it must not be quoted as a complete account of the division.

What does a split not decide?

A service split is a change in the published categories. It is not a decision about a specific unit. The correspondence table records the scopes where one old group or class becomes two or more new classes, and the explanatory note for each new class states its inclusions and exclusions. Neither document picks a new class for a specific unit. The classification is statistical only. Tax, licensing, social security, collective agreements and funding eligibility are not settled by this classification, and the institute or register holding the record confirms the entry for a unit.

Where is a split class confirmed?

The check for a split class runs in three steps. First, the section 4 summary in the manual for the change as adopted. Second, the explanatory notes for the new classes, for inclusions and exclusions. Third, ask the institute or register for the entry actually held. The first step is supplied here, and the other two are pointed to.

Separate libraries, museums, conservation support and gardens by the group notes, follow the inbound exclusions from other divisions, and confirm the entry with the institute or register that holds it.
