These municipalities in the Amsterdam metropolitan area (MRA) were each presented with a Madaster material passport for one of their buildings.' Named: Amsterdam, Almere, Diemen, Edam-Volendam, Haarlem, Lelystad, Uithoorn and Waterland.",

Each passport covers one building per municipality, not a municipal portfolio, and the MRA reaches well beyond Amsterdam (Almere, Lelystad). The account is the platform operator's own.",
