Events are an essential component of cultural heritage Linked Data: they link actors, places, times, objects, and other events into larger narrative structures, providing a rich basis for semantic searching, recommending, analysis, and visualization of cultural heritage data. This paper argues that shared vocabularies (gazetteers, ontologies) of events, such as the “Battle of Normandy” or “Crucifixion of Jesus”, are necessary to facilitate the aggregation and linking of heterogeneous content from various collections. For example, biographies, histories, photos, and paintings often reference or depict events. A set of general requirements for an event gazetteer is presented, based on the needs of publishing, aggregating, and reusing cultural heritage content as Linked Data. After this, a metadata model addressing the presented requirements for representing historical events is outlined. The model is being applied in a case study aimed at developing an event ontology for World War I (WWI). Our goals from an end-user perspective are twofold: 1) Facilitate event-based cataloging for curators in memory organizations; 2) Utilize semantic event descriptions and narrative event structures in end-user applications for searching and linking documents and other content about WWI, and for structuring and visualizing them.
