An item split is required when an item includes sitelinks and/or statements that belong to different concepts that would be better managed by two separate items. It is the opposite of the merge operation.
A split can be performed manually, or by using the move-claim-script or the duplicate-item-script. This page provides guidelines for performing the operation.
Preliminary checks
- 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.
How to manually split an item into two items
In order to retain existing references on statements that are to be transferred to a new item, follow the procedure below:
- Create a new item
- Merge the existing one into it
- Remove all sitelinks from the target item
- Modify labels and/or descriptions of the target item (two items are not allowed to be exact duplicates)
- Restore the original item from its history
- Manually move appropriate sitelinks from the old item to the new one
- 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)
- Delete or fix incorrect statements on both items
- Check the incoming links of the old item (through Special:WhatLinksHere) and fix the incorrect ones, so that they link to the new item
