DCCD stands for Digitaal Collaboratorium voor Culturele Dendrochronologie (Digital Collaboratory for Cultural Dendrochronology). This international digital data library of annual growth ring data contains digital growth ring series and mean chronologies, as well as their descriptive and interpretative metadata. The content is developed by research from archaeological sites (including old landscapes), shipwrecks, buildings, furniture, paintings, sculptures and musical instruments. The archive contains data from European institutes, such as the Cultural Heritage Agency, Wageningen University, Sheffield University, the Royal Institute for Cultural Heritage (KIK-IRPA) and DendroNet.
Together with the RCE, DANS ensures that the data from the technically outdated DCCD portal can be found and accessed via DataverseNL from April 2021.
