culturegraph: "culturegraph.org is a Linked Open Data service that aims to establish shared identifiers (Uniform Resource Identifiers) for cultural works (books and other text, paintings, sculptures, piece of music etc.) to ensure these resources can be reliably and persistently referenced. The service is currently being developed cooperatively by the German National Library (DNB) and the North Rhine-Westphalian Library Service Center with support from the German-speaking Working Group of Library Networks."
