Will a standard bearer like OCLC or LC provide this, or will this be something that libraries will provide?
  5. 5. Agenda • Overview of linked data –What is linked data? –What are linked data concepts? • Discussion
  6. 6. •Linked data is: “about using the Web to connect related data that wasn't previously linked, or using the Web to lower the barriers to linking data” •Think> related, series records, authority files •Libraries already using linking behavior •Projects such as the NYT Linked Open Data project and the Virtual Authority File project are resources of controlled vocabularies •Verified and digital identity accounts such as openID and claimID to differentiate names

  8. 8. • Advantages • Reusable data • Potential to provide and build relationships • discoverability • How library data fits into linked data o FRBR-- a bibliographic FRAMEWORK which is more semantic by nature o RDA (Resource Description & Access metadata rules which are not tied to a programming language such as MARC but can work with semantic web standards like XML o IRs, and CMS like Drupal which have semantic web capabilities • RDA expressed as RDFa
  9. 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 data o We already do some linked data in our library catalogs and even in our daily lives o The link in a bibliographic record (like an authority record link) is linking data behavior o A link that we share to our friends on facebook is linked data (of sorts) • Linked data is a link to a record/data/content that can then be utilized in some way • Open data is data that available to be used in some way with no barriers to access (licensing, etc.)
  10. 10. The RDF Triple: conceptual Examples same as author of Predicate/verb
  11. 11. Tim Berners-Lee’s Four Rules 1. Use URIs as names for things 2. Use HTTP URIs so that people can look up those names 3. When someone looks up a URI, provide useful information, using the standards 4. Include links to other URIs, so they can discover more things URIs = Uniform Resource Identifier
  12. 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 FAST as 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 more consistent data – allowing for collocation across resources and allowing users to easily find resources regardless of source

It will allow us to move forward into the semantic web world RDA, FRBR, and MARC
