This deliverable reports on work carried out within SSHOC Task 5.6 - Issues in providing Open Data in Heritage Science and Archaeology. It focusses specifically on issues related to working with Heritage Science data and examines the accessibility and interoperability of such data. Starting with two distinct, but related, non-standard datasets, covering the documentation and study of old master paintings, the work created new fully semantic, linkable, shareable, machine-readable FAIR datasets mapped to the standard CIDOC-CRM ontology and other external Linked Open Data resources.
