Help:Split an item

An item split is required when an item is conflated.

A split can be performed manually, or with the help of the duplicate-item-script; other useful gadgets are mentioned below. This page provides guidelines for performing the operation.

• Verify if the item mix-up results from a recent merge. If this is the case, restore the pre-merge version, then restore the pre-merge version of the other item.

In order to retain existing references on statements that are to be transferred to a new item, follow the procedure below:

1. Create a new item
2. Merge the existing one into it
3. Remove all sitelinks from the target item
4. Modify labels and/or descriptions of the target item (two items are not allowed to be exact duplicates)
5. Restore the original item from its history
6. Move appropriate sitelinks from the old item to the new one (you can use the "Move" gadget). If a Wikipedia article describes both concepts, you may use an intentional sitelink to redirect (Q70894304) to link both the old and the new Wikidata item to the same Wikipedia article. A typical example is a Wikipedia article that conflates a building and the organization operating it. For more information, see the documentation in WikiProject Cultural venues.
7. Fix labels of "moved sitelink" languages (or at least delete them); you may reproduce these labels on the new item (but bots would do that shortly using sitelinks)
8. Move incorrect statements from the old item to the new one (you can use the "moveClaim" gadget)
9. Check the incoming links of the old item (through Special:WhatLinksHere) and fix the incorrect ones, so that they link to the new item
