EUROPEANA & vocabularies
• EUROPEANA will be integral part of the Web of Knowledge
• Linked Data – the RDF Web, Web as a database
• Building units: URIs (Uniform Resource Identifiers) in RDF (Resource Description Framework) triplets:
Subject, Predicate, Object
• Vocabularies as Hubs in the Web of Knowledge: Vocabularies as Hubs in the Web of Knowledge: SKOS – Simple Knowledge Organisation System
Tagging content with controlled vocabularies:Irish vocabulary on Vikings
Tagging content with controlled vocabularies:Norwegian vocabulary on Vikings
Mapped vocabularies – semantic graphs

The award-winning Where Once We Walked (WOWW) has been completely revised and updated to reflect the changes in the political geography of Central and Eastern Europe since WOWW was published in 1991. There are also a number of improvements to the original edition noted below. The new edition identifies more than 23,500 towns in Central and Eastern Europe where Jews lived

Tasks for a common agenda on Jewish vocabularies
• Who? 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

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 toconcepts:skos: prefLabel [descriptor]skos: altLabel [synonims, acronyms, abbreviations]
SEMANTIC RELATIONSHIPS…broader and narrower conceptsbroader/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 propertiesexactMatch, broadMatch, narrowMatch and relatedMatchApr 10, 20
