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:
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

• Who? Names
Tasks for a common agenda
on Jewish vocabularies
• 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,
and published on the Web
CONCEPTS
composed, integrated
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
relationship to link a
compiled sets of concepts: ConceptScheme class and inScheme
concept to a scheme
hasTopConcept relationship for the entry points of narrower/broader
hierarchy
LINK schemes
May the
17 properties
map concepts from different schemes using
exactMatch, broadMatch, narrowMatch and relatedMatch
