Motivation

This would be useful for lighthouses, and possible some other equipment. It's about the only property that we are missing from the infobox template at enwiki. Alternatively item operated (P121) could be used with some qualifier, but I'm not sure how well that fits. — Martin (MSGJ · talk) 12:01, 14 May 2021 (UTC)

•  Done @MSGJ, Arbnos: please help complete the property and ensure that it's being used. --- Jura 12:08, 21 May 2021 (UTC)

  Thanks. I've added the examples above. Will work through others when I get time. — Martin (MSGJ · talk) 12:23, 21 May 2021 (UTC)
