Change Details

Some templates on Commons like for example https://commons.wikimedia.org/wiki/Creator:Jan_Ekels_%28II%29 link to Wikidata items. I merged the item this template is pointing to. I'm looking for a LUA function to check if a certain item (in this case "Q18516596") is a redirect and what the target item is (in this case "Q2450553"). Maybe this is already possible, but couldn't find it anywhere in the documentation.
