The document discusses challenges and opportunities for libraries to publish their data as linked open data on the semantic web. It provides examples of libraries that have begun publishing authority files, catalog data, and thesauri as linked open data. The document also outlines advantages of the semantic web for libraries and potential applications that could make use of linked library data.

Rdf and open linked data a first approach
- 1. RDF and Open Linked Data, a first approach ADLUG Users Group Meeting Trento , 22 - 24 September, 20 10 Tiziana Possemato, @C ult Andrea Gazzarini , @Cult Ádám Horváth , NSZL
- 2. Contents Open Linked Data ThGenius Thesaurus management in WeCat Keyword search enrichment
- 3. Chalanges for libraries Les and les people use library catalogues What could be the answer To bring the catalogue to the surface web To make it searchable by Google To provide your data where the user is The user must be able to get library data in social sites To provide your data on mobile equipments
- 4. Challenges for libraries New potential user: the web and the services on the web Our services must not only be on the Web, but need to be of the Web We have to publish our data on the semantic web We can use semantic web technologies
- 5. Some introductory notes Semantic web is often called Linked Data Open Linked Data Linked Open Data (LOD) the web of Linked Open Data
- 6. Web and semantic web Web links pages Semantic web links data Web is like a document Semantic web is like a database RDF is the data format of the database This database is independent from any application Web is for human beings Semantic web is for machines
- 7. Advantage of linked data Linked data provides a single, standardised access mechanism Linked data is a single worldwide API
- 8. Advantage of semantic web technologies Certain tasks can be carried out easier with semantic web technologies RDF database + SPARQL = very powerful search capabilities
- 9. Linked data from library perspective Libraries can share data in a non library centric way Libraries can share their data in a web friendly way Library’s data can be meaningful in a new context
- 10. The role of libraries in building the semantic web The libraries have to publish their data on the semantic web Software developers have to develop applications that use the (published) semantic data Libraries can use semantic web technologies, applications to solve certain tasks more efficiently Library vendors can help on both sites
- 11. Libraries publishing linked data Entire library LIBRIS National Széchényi Library (NSZL)
- 12. Libraries publishing linked data Authority files Library of Congress Subject Headings in SKOS format Deutsche Nationalbibliothek Name authority and subject heading authority in its on format VIAF (Virtual International Authority File) MARC based but also publishes data in FOAF format NSZL is also participating in VIAF
- 13. Libraries within W3C W3C Library Linked Data Incubator Group http://www.w3.org/2005/Incubator/lld/ Chairs Tom Baker Emmanuelle Bermes Antoine Isaac
- 14. Semantic web application s Semantic search
- 17. Semantic web applications works showing matching person works showing location works showing concept works titled works created from works with matching location works showing a more specific location
- 18. Vocabularies Dublin Core ( DC ) defines general metadata attributes. See also their new domains and ranges draft. Friend-of-a-Friend ( FOAF ), vocabulary for describing people. Simple Knowledge Organization System ( SKOS ), vocabulary for representing taxonomies and loosely structured knowledge. Bibliographic Ontology ( BIBO ) Expression of Core FRBR Concepts in RDF
- 19. Linked data in ADLUG’s 2008 Venice: First steps towards publishing library data on the semantic web 2009 Bilbao: Semantic web tutorial 2009 Bilbao: Using Cool URI’s as permalink ADLUG is a leader of spreading the idea of semantic web in libraries
- 20. [email_address] Thank you for your attention
- 21. NSZL’s results so far In this spring NSZL published as linked open data Its entire catalogue of the library and digital libra r y in RDFDC format Its name authority in FOAF Its geo g raphical and subject term thesaurus in SKOS
- 22. NSZL’s plans Using OAI-ORE for describing compound digial objects in our digital library Using semantic web technologies in showing the FRBR work tree in our LibriVision OPAC
