Which activities remained in Section K from division 63?

The rest of division 63, after the move of news agency and postproduction conversion work to Section J, remained in the new Section K. Paragraph 165 states the division of the division. The remaining content sits in two groups: group 63.1 for computing infrastructure, and group 63.9 for web search portals and other information services. The statement is structural. A specific reader code is not determined here.

What does the remainder contain?

Paragraph 171 states that a new group 63.1, computing infrastructure, data processing, hosting and related activities, containing a single class 63.10 of the same title, was created. The group includes cloud infrastructure and platform provision, cloud computing except software publishing and computer systems design, blockchain and distributed ledger technology data processing activities, and technical infrastructure provisioning services related to streaming. The list is taken from paragraph 171, and the full inclusions and exclusions are in the explanatory note for class 63.10, covered in the new classes cluster.

Paragraph 172 states the second group. A new group 63.9, web search portal activities and other information service activities, contains two classes: class 63.91, web search portal activities, and class 63.92, other information service activities, formerly class 63.99, other information service activities not elsewhere classified. Class 63.92 was created to cover activities of web sites that use a search engine to generate and maintain extensive databases of internet addresses and content in an easily searchable format, as part of the former class 63.12, web portals. The group therefore holds the search and general information service work that did not move to Section J.

How does the remainder relate to the moved content?

The remainder and the moved content are separated by the content boundary described in the Section J and Section K guides. Work that produces or distributes content sits in Section J. Work that provides the infrastructure, the search facility or the general information service sits in Section K. The explanatory note for class 63.10 states the boundary from the infrastructure side: it excludes software publishing, postproduction conversion services, and streaming and download distribution service activities not associated with publishing, each to its stated category in Section J. The note for group 63.9 likewise excludes news agency activities to class 60.31.

The boundary is not a judgement about importance. Infrastructure work and content work are both recorded in the classification, in different sections, because the manual groups activities by the character of the work, not by its commercial weight. A reader who treats a streaming infrastructure service as a content distribution service, or the reverse, has crossed the boundary the manual draws. The notes for the two sides, read together, show where the line falls for the activity in question, in general terms. The entry for a specific unit is confirmed by the institute or register.

How is the remainder laid out?

| Group | Classes | Content in the manual summary |

|---|---|

| 63.1 | 63.10 | Computing infrastructure, data processing, hosting and related activities |

| 63.9 | 63.91, 63.92 | Web search portal activities and other information service activities |

The table follows paragraphs 171 and 172. Group 63.1 has one class. Group 63.9 has two classes. The asymmetry is a feature of the structure as adopted: the computing infrastructure group was created as a single class group, while the search and information group carries the two classes that survived the restructuring. The table does not list further classes, because the manual summary lists no further classes in these groups.

What does the split not decide?

The split changes the structure of the classification. Because a code has no legal effect beyond statistical use, its legal effect is unchanged by this. Eurostat and the EUR-Lex summary both confine the legislation to statistical purposes. First questions for an old Section J code in a dataset: which classification version does the dataset use, and what does the correspondence table say about the move? Neither question is answered by the letter alone, nor by this guide for a specific unit.

Where is a moved code confirmed?

Confirmation here means three checks in order. First, the section 4 summary in the manual for the structural change. Second, the explanatory notes for the categories at each end of the move. Third, the institute or register for the entry held for a specific unit. The first check is supplied here, and the other two are pointed to.

Keep the infrastructure and search work in groups 63.1 and 63.9, keep the content work in Section J, and confirm the entry with the institute or register that holds it.
