Names • Disseminate the use of VIAF • Seek to include periodical publications in VIAF • RAMBI • Long term common effort to achieve comprehensiveness • Where? Places • JewishGen and Yad Vashem gazetteers as linked data? • Use Europeana guidelines to map places coordinates • Registry of Jewish gazetteers / RDF/ community based Jewish gazetteer service similar to GeoNames, Freebase, LinkedGeoData etc • When? Periods • Survey available vocabularies and seek to express them as Linked Data • Institutional tools for in-depth probe on current periodisation practices http://www.judaica-europeana.eu/docs/jewish_vocabularies_LOD.pdf

  22. 22. EDM Europeana Data Model Guus Schreiber with input from Carlo Meghini, Antoine Isaac, Stefan Gradmann, Makx Dekkers et al. from Europeana V1
  23. 23. Outline
  24. 24. EDM requirements 1. Distinction between “provided object” (painting, book, program) and digital representation 2. Distinction between object and metadata record describing an object . 3. Allow for multiple records for same object, containing potentially contradictory statements about an object 4. Support for objects that are composed of other objects 5. Standard metadata format that can be specialized 6. Standard vocabulary format that can be specialized 7. EDM should be based on existing standards – “not yes another standard” !
  25. 25. dov.winer@gmail.com SKOS Simple Knowledge ORGANIZATION SYSTEM thesauri, classifications, subjects, taxonomies, folksonomies,… controlled vocabulary concepts are documented, linked, merged with other data, composed, integrated and published on the Web CONCEPTS identified by URIs using RDF triples natural language expressions to refer to concepts: skos: prefLabel [descriptor] skos: altLabel [synonims, acronyms, abbreviations] SEMANTIC RELATIONSHIPS …broader and narrower concepts broader/narrower relationships assert that a concept is broader/narrower in meaning …concepts somehow related SCHEMES compiled sets of concepts: ConceptScheme class and inScheme relationship to link a concept to a scheme hasTopConcept relationship for the entry points of narrower/broader hierarchy LINK schemes map concepts from different schemes using the properties exactMatch, broadMatch, narrowMatch and relatedMatch May 14
  26. 26. OAI ORE Open Archives Initiative Object Reuse & Exchange • Specification: http://www.openarchives.org/ore/1.0/toc.html • Primer: http://www.openarchives.org/ore/1.0/primer • Specified with an RDF model • Four key notions (RDF classes) – Object: the book/painting/program being described – Aggregation: organizes object information from a particular provider (museum, archive, library) – Digital representation: some digital form of the object with a Web address – Proxy: the metadata record for the object
