Help:Conflation of two persons

From Wikidata
Jump to navigation Jump to search

Once in a while, we may come across items that conflate two or more persons. Such amalgamation can happen when people have similar names and are active in related fields. It may be an internal issue at Wikidata or reflect confusion at Wikipedia or other sources. What to do?

Identify[edit]

An item conflates two people when it includes several elements that come from each, notably the dates of one and the achievements or function of another.

This is different from an item that merely includes a fact about another person.

In case of a conflation, identify this on the item:

Create new items[edit]

First create new items for each person,

then move statements from the original item to the correct one.

  • If an identifier is defined with elements of both persons, leave it on the original item.
  • If a reference mentions a fact of one person, but attributes it to the other, add it also with deprecated rank to the other.

Update internal links[edit]

Check the links from other items and update them to the new item about the correct person.

Result[edit]

Delete[edit]

If all statements were moved to the new items, the original item can be deleted. Please list it on Wikidata:Deletion requests with the explanation "[[Help:Conflation of two persons|conflation]], split into [[Q1]] and [[Q2]]".

It may be tempting to redirect the original item to one or the other new item, but this may lead users of the original item to refer to the wrong person.

Keep[edit]

The original item should be kept if some identifiers remain. This avoids that:

  • identifiers are re-added to the wrong item
  • people using these identifiers add statements to the wrong item

Descriptions should be deleted or updated to indicate "conflation".
