The Semantic Web allows data to be linked on the Web and structures information for use by humans and machines. Furthermore, it makes relationships between data explicit, enabling the creation of Linked Data.

Europeana aggregates European institutions’ digital cultural heritage, having developed a model that follows linked-data principles.
