Use HTTP URIs so that people can look up those names.3. When someone looks up a URI, provide useful information, using the standards. (RDF*, SPARQL)4. Include links to other URIs. so that they can discover more things. 10 11. Linked Data 4 1 1. Use URIs as names for things. URI 11 12. Linked Data 4 2 2.

MOLTO Requirements:- the ability to handle generic knowledge, such as people, institutions, and locations- the ability to handle specific subject domains, such as the cultural heritage andmuseums Ontology & Interlinking- DBpedia - the RDF-ized version of Wikipedia, describing more than 3.5 millionthings and covers 97 languages.- Geonames - a geographic database that covers 6 million of the most significantgeographical features on Earth.- PROTON - an light weight upper-level ontology, 542 entity classes and 183properties. PROTON is encoded in OWL Lite- CIDOC-CRM- Painting Ontology (Time Ontology, Mid-Level-Ontology SUMO)- Linkages to DBpedia http://www.molto-project.eu 44 45.

Europeana http://europeana.eu Pan-European Digital Museum People can explore the digital resources of Europesmuseums, libraries, archives, audio-visual collections And be inspired by the rich diversity of Europes cultural and scientific heritage Promotes discovery and networking opportunities in amultilingual space Around 1500 institutions contributed Includes over 15 M items53 54. Europeana and Semantic WebEuropeana adopts semantic web for all future development EDM is based on semweb, which makes it easily extensible Current holdings will be converted to semweb formatEuropeanas first White Paper Knowledge = Information in Context looks at the key role LOD will play in Europeanas development "Linked data gives machines the ability to make associations and put search terms intocontext. Without linked data, Europeana could be seen as a simple collection of digital objects.With linked data, the potential is far greater"LOD Experiment in Europeana Thought Lab: Data and metadata from the Amsterdam Museum (AM) 70k cultural heritage objects related to the city Retrieved from an XML API of the museums collection (database by AdLib UK) Converted to LOD compliant with EDM by Vrije Universiteit (VU): 5M f
