Archaeological documentation from surveys and excavations in Norway are created by a limited number of actors. Excavations are mainly carried out by the five university museums. NIKU (Norwegian Institute for Cultural Research) is responsible for excavations of medieval cities and churches. Maritime museums excavate in lakes, rivers, and below past and present sea level. Archaeological surveys are mainly the responsibility of the counties. Riksantikvaren (Directorate of National Heritage) is responsible for the national Historic Environment Records (HER), Askeladden, which offers the possibility to upload or insert links to reports from archaeological investigations. Riksantikvaren also archives excavation documentation from churches and medieval cities. The Norwegian university museums have, since the 1990s, cooperated on digitising a national repository and making the collections available online. Presently there are also repositories at the maritime museums, Riksantikvaren and the counties. The infrastructure ADED (Archaeological Digital Excavation Documentation) is a repository for detailed excavation documentation, and the BItFROST infrastructure project contributes to better storage and availability of 3D data. Future development will be more complete national databases, and towards closer international cooperation, creating better integration and availability of several repositories.
