Amsterdam Museum als Europeana Linked Open Data Victor de Boer -- VU Amsterdam Met Antoine Isaac, Jan Wielemaker, Jacco van Ossenbruggen Michiel Hildebrand en Guus Schreiber
Europeana “Europeana enables people to explore the digital resources of Europe's museums, libraries, archives and audio-visual collections.’’ Huidige versie verzamelt alle metadata van instellingen in dublin core velden (Europeana Semantic Elements). Goed voor textueel zoeken, maar: Geen relaties tussen objecten, concepten, plaatsen, namen. Term/taal-afhankelijk Rijke originele metadata wordt ‘platgeslagen’ www.europeana.eu
Europeana Data Model Doelen van EDM Behoud van originele metadata Gebaseerd op semantic web principes (resources, URI’s, RDF, links) Gebouwd op bekende standaarden OAI ORE (proxy, aggregation, physicalObject) Dublin Core voor metadata representatie (plus Europeana-specifieke properties) SKOS voor vocabulaires
EDM voorbeeld Provenance +web views/plaatjes proxy object metadata Aggregation Physical Object geen metadata
Cliopatria Conversie stappen Tools ontwikkeld om van originele cultural erfgoed metadata naar EDM data te komen (+ Linked) (+ Open data) Stappenplan  Start met XML (of OAI-harvest) Syntactische transformatie naar RDF Herschrijf de ruwe RDF Definieer een schema dat classes/properties  naar EDM classes/properties mapt Link naar Europeana en externe bronnen Publiceren als LOD XMLRDF Amalgame
