Since its conception in 2011, the international community of the International Image Interoperability Framework (IIIF) has taken important steps in improving the way cultural heritage institutions (CHIs) present images on their digital collections platforms.
Since the foundation of various libraries close to the university in the 14th and 15th centuries, the Universitätsbibliothek Heidelberg has housed many important collections. The datasets that have been delivered to Europeana hold over 25,000 records including treasures such as manuscripts, manuscript fragments, charters, and early modern and modern printed books and magazines.
Europeana has progressively adopted the principles of Linked Data for representing, aggregating, and enriching the metadata it collects from the Cultural Heritage institutions of Europe. Its foundation is the Europeana Data Model (EDM) which enables the representation of links between cultural heritage objects and the entities surrounding them (people, places, concepts, timespans).
