Will a standardbearer like OCLC or LC provide this, or will this besomething that libraries will provide?
  • 5. Agenda• Overview of linked data–What is linked data?–What are linked data concepts?• Discussion
  • 6. •Linked data is: “about using the Web toconnect related data that wasntpreviously linked, or using the Web tolower the barriers to linking data”•Think> related, series records, authorityfiles•Libraries already using linking behavior•Projects such as the NYT Linked OpenData project and the Virtual Authority Fileproject are resources of controlledvocabularies•Verified and digital identity accountssuch as openID and claimID todifferentiate names

  • 8. • Advantages• Reusable data• Potential to provide and build relationships• discoverability• How library data fits into linked datao FRBR-- a bibliographic FRAMEWORK which is more semantic bynatureo RDA (Resource Description & Access metadata rules which are nottied to a programming language such as MARC but can work withsemantic web standards like XMLo IRs, and CMS like Drupal which have semantic web capabilities• RDA expressed as RDFa
  • 9. What is linked data and open dataWhat is linked data and open dataWhat is linked data and open dataWhat is linked data and open data????o Linked data is about reusing datao We already do some linked data in our librarycatalogs and even in our daily liveso The link in a bibliographic record (like an authorityrecord link) is linking data behavioro A link that we share to our friends on facebook islinked data (of sorts)• Linked data is a link to a record/data/content thatcan then be utilized in some way• Open data is data that available to be used in someway with no barriers to access (licensing, etc.)
  • 10. The RDF Triple:conceptual Examplessame asauthor ofPredicate/verb
  • 11. Tim Berners-Lee’s Four Rules1. Use URIs as names for things2. Use HTTP URIs so that people can look upthose names3. When someone looks up a URI, provide usefulinformation, using the standards4. Include links to other URIs, so they candiscover more thingsURIs = Uniform Resource Identifier
  • 12. What can linked data do for libraries?• URIs creates methods for classifying that can be used(linked to!) by others• Library of Congress has released LCSH as linked data,and OCLC has a modified version of LCSH called FASTas linked data• Linked Data is flexible enough to express entity-relationship relationships such as FRBR/FRAD• Different databases (ILS, ERMS, IRs, local databases,etc.) allowing sharing of data – potentially moreconsistent data – allowing for collocation acrossresources and allowing users to easily find resourcesregardless of source
