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

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

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
