Semantic Web, Linked Data: the Europeana case(s)
The document discusses the Europeana project, which serves as Europe's cultural heritage portal, aggregating diverse collections from various galleries, museums, and libraries. It emphasizes the development of a new Europeana Data Model for improving metadata management through linked data and semantic web principles, including collaboration with experts from different sectors. The document also highlights the challenges and opportunities for enriching metadata and facilitating reuse while adopting innovative technologies to enhance access to cultural content.

- #19 Data is available as ‘data dumps’ for Linked Open Data initiatives from data.europeana.eu. Europeana&apos;s move to CC0 is a step change in open data access. Releasing data from across the memory organisations of every EU country sets an important new international precedent, a decisive move away from the world of closed and controlled data. Note that previews can only be used in accordance with the rights information displayed next to them. HISPANA and Partage Plus both use the Europeana API to include Europeana search results on their own websites
