This document discusses augmenting content in Europeana, a digital library of European cultural heritage, with linked data resources. It describes tools for video and map annotation that integrate user annotations with linking to external resources. Annotations are exposed as linked data on the web using common vocabularies and are linked to databases like DBpedia to provide additional context and multilingual retrieval capabilities. Future work aims to improve integration with retrieval systems and investigate uses for map annotation and geo-referencing.
