    Linked data as a library data platform Linked data as a library data platform Presentation Transcript

    • Linked Data as a Library Data Platform A Proof of Concept from National Technical Library of Czech Republic Jindřich Mynarz National Technical Library ELAG 2010 Helsinki June 10th 2010
    • Overview  Library data  Linked data  Converting library data to linked data  Distribution  Benefits of linked library data
    • Library data are not very readable
    • Source: National Library of the Czech Republic card catalogue Catalog card - record
    • MARC Record CAPTCHA - Completely Automated Public Turing test to tell Cataloguers and Humans Apart
    • Library data in XML are still not very readable
    • Library-specific access protocols (Z39.50, OAI-PMH)

    • ttp://www.flickr.com/photos/dullhunk/303503677 Linked data
    • Linked data principles Thou shalt:  Use URIs as names for things.  Use HTTP URIs so that people can look up those names.  When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL).  Include links to other URIs. so that they can discover more things.

    • Data conversion  Choosing datasets  Choosing description  Extraction  Linking  Distribution
    • Choosing description  Domain ontologies  Established, popular (Dublin Core, SKOS) Falcons concept search
    • http://blissfullydomestic.com/2010/spring-clean-your-blog-comments Extraction - matching dirty data
    • Linking Library data already contain links
    • Links to resources identified by code values
    • Links to classification notations
    • Links to persons
    • Links to geographical entities and institutions
    • „Outsourcing“ authorities  DBPedia  VIAF  Geonames
    • http://thesecretmirror.com/linked-data/why-you-should-support-linked-data Crawling data
    • Distribution  Lightweight API  Single interface to the datasets
    • http://www.flickr.com/photos/virtualsugar/316200555 Open bibliographic data
    • Open licences
    • National Technical Library's library linked data prototype http://www.panoramio.com/photo/20268409  Incomplete  Parallel coexistence with the original way of data distribution
    • Benefits of linked library data  Readable  Sharable  Linkable  Distributable  Integrable  ?-able
    • Changes
    • Questions!
