The Swiss National Museum is home to about a million objects of Swiss heritage. These objects are catalogued, restored and exhibited in collections, with the goal of preserving and making accessible the cultural heritage of Switzerland. Since 1989, the museum has been working a 4D object-based management system for its million items. The solution covers cataloguing, registration, property management, rental systems, publications, storage, image management, transportation, planning, and collections. Based on 4D v12, this central object and information management system is used by around 40 users every day.
