This is a company doing extra stuff with the data, and providing some of it directly online. Here's a lookup of the company I work for: https://proff.no/aksjon%C3%A6rer/bedrift/oda-group-holding-a...
It lists owners, but as you can see it's mostly "Holding Companies". However, pressing "Indirekte eierskap og eiere" ("Indirect ownerships") one can see the true companies or persons behind those.
