The Norwegian university museums cooperate in National data infrastructures for archaeology. The new web-based user interface for the Archaeology system was launched in January 2024, following the completion of the new system for Numismatics in 2021 and Ethnography in 2022. This work included migration of data from the Delphi-based MUSIT database to the new UniMus database, which is a Postgres system using an event-based datamodel. Data from all museums is published at the Unimusportal (unimus.no/portal) and is also downloadable from unimus.no. This georeferenced archaeological data from UnimusArk is also made available through the Ariadne portal (https://portal. ariadne-infrastructure.eu/). Another part of the National infrastructure is ADED (Archaeological Digital Excavation Documentation). ADED mainly contains detailed GIS excavation information from 2011 onwards and includes links to excavation photos and artefact records held in the other shared databases. Earlier excavations will be included later. The Museum of Cultural History (MCH), in close cooperation with DARK Lab (darklab.lu.se) at Lund University and the Visual Computing Lab (ISTI –CNR) has developed the BItFROST platform, based on 3DHOP, for the museum’s 3D models. It is currently used for 3D models of artefacts, but extended applications will also include excavation data. The possibilities for sharing annotations and commented models are important features of BItFROST and there is potential for this system to be developed into another element of the national infrastructure. MCH has come a long way in making its archaeological data FAIR. The aspect of reusability is especially receiving special attention this year through the project UI3D (Understanding and Immersion in 3D). UI3D aims to address reuse and active use of Heritage Data in Teaching and Research. It is funded by the University of Oslo’s framework for competence hubs in IT research and will interact with the ERASMUS+ cooperation Virtual Worlds Teaching in Archaeology.
