Editing an existing claim via the API wbsetclaim module will result in creating a new claim. An API call looks like: /mediawiki/core/api.php?action=wbsetclaim&format=json&claim=%7B%22type%22%3A%22claim%22%2C%22mainsnak%22%3A%7B%22snaktype%22%3A%22value%22%2C%22property%22%3A%22p1110%22%2C%22datavalue%22%3A%7B%22type%22%3A%22wikibase-entityid%22%2C%22value%22%3A%7B%22entity-type%22%3A%22item%22%2C%22numeric-id%22%3A2647%7D%7D%7D%2C%22id%22%3A%22q2647%24574052AD-1518-4CD3-A21C-637837C7C040%22%2C%22qualifiers%22%3A%7B%7D%7D&token=%2B%5C&baserevid=17420 The API result seems to be correct: { "pageinfo": { "lastrevid": 17426 }, "claim": { "id": "q2647$574052AD-1518-4CD3-A21C-637837C7C040", "mainsnak": { "snaktype": "value", "property": "p1110", "datavalue": { "value": { "entity-type": "item", "numeric-id": 2647 }, "type": "wikibase-entityid" } }, "type": "claim" } } However, featuring one claim in the beginning, the entity will have two claims now which can be verified in the UI. The operation seems to mess up the revisions since removing a claim via the UI seems to trigger the "remove" action on a wrong revision.
