The Art Datis project, launched in September 2018, was originally conceived as a four-year project involving two PhD candidates: an art historian and glass artist (Anna Carlgren) and a data scientist (Vera Provatorova). Their task was to examine Valkema's archive, which includes everything from personal letters and administrative documents to glass recipes and correspondence with other artists. This archive, covering the postwar period until Valkema's death in the 1990s, offers a comprehensive overview of his contributions to glass art.

The Semantic Web needs interfaces for critical, reliable analyses of Big Data for research in humanities, cultural heritage, and creative industries. Utilizing data on the production and consumption of cultural goods, geodata, maps, and building plans from the Golden Age, the project 'Virtual Interiors' unlocks the research potential of large historical data in a geospatial context. The project is funded by NWO Smart Culture – Big Data/Digital Humanities.
