2. • Europeana / DPLA: Sources of Curated Quality
Content
- part of the Linked Data cloud
• Tools support the use of the content and create
context
- Hackatons vs Mature tools development
• Two mature tools: Annotation (Pundit) and Storytelling
(Movio)
• Vocabularies as embedded knowledge: crystal seeds
in the ocean of Linked Data

Jewish Knowledge in the
Structured Web

29. Who?

30. When?

31. Jewish gazetteers
Where?

32. Jewish encyclopedias: CONTEXT
The goals of the project
Linking and Populating the
Digital Humanities are to
create and maintain data
integration tools tailored to
digital humanities collections in
order to build a machine-
readable web of facts about
covered domains.

33. Jewish encyclopedias: CONTEXT
Encyclopedia Judaica
Encyclopedia of Russian Jewry

Rav Zeev Vagner
Josh Kopelman

34. 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

36. EDM
Europeana Data Model
Guus Schreiber
with input from Carlo Meghini, Antoine Isaac, Stefan Gradmann,
Makx Dekkers et al. from Europeana V1

37. Outline

38. 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” !

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

41. 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
