RKD-Knowledge-Graph

We manage unique archives, documentation and photographic material and the largest art historical library on Western art from the Late Middle Ages to the present, with the focus on Netherlandish art. Our collections cover not only paintings, drawings and sculptures, but also monumental art, modern media and design. The collections are present in both digital and analogue form (the latter in our study rooms). This [knowledge graph](https://en.wikipedia.org/wiki/Knowledge_graph) represents our collection as Linked Data, primarily using the [CIDOC-CRM](https://cidoc-crm.org/html/cidoc_crm_v7.1.1.html) and [LinkedArt](https://linked.art/model/) vocabularies.
