  • For each part a URI.
  • URIs are kind of like a hook – they allow us to connect things together.

  • 1. Linked Data: What it Meansfor the Future of LibrariesRobin Fay @georgiawebgurlHead, DBM/Cataloging / UGA LibrariesPeter MurrayLyrasisDraft Content for Discussion group 04.30.2013 / robinfay
  • 2. Agenda• Overview of linked data▫ What is linked data?▫ What are linked data concepts?▫ Background: Alistair Croll talk at ALA Midwinterhttp://www.youtube.com/watch?v=Ic_BlPesEls• DiscussionDraft Content for Discussion group 04.30.2013
  • 3. •Linked data is: “about using the Webto connect related data that wasntpreviously linked, or using the Web tolower the barriers to linking data.”•Think> related, series records,authority files•Libraries already using linkingbehavior.•Projects such as the NYT Linked OpenData project and the Virtual AuthorityFile project are resources ofcontrolled vocabularies.•Verified and digital identity accountssuch as openID and claimID todifferentiate namesDraft Content for Discussion group 04.30.2013
  • 4. Basic principles of linked dataIt keeps us from having to re-enter or copy information▫ Making our data: reusable easy to correct (correct one record instead ofmultiples) efficient and potentially useful to othersIt can build relationships in different ways - allowing us tocreate temporary collections (a user could organize theirsearch results in a way that makes sense to them) or morepermanent (collocating ALL works by a particular authormore easily; pulling together photographs more easily)Draft Content for Discussion group 04.30.2013
  • 5. • Advantages (reusable data, potential to provide andbuilt relationships, discoverability)• How library data fits into linked datao FRBR ( a bibliographic FRAMEWORK which is moresemantic by nature) RDA (Resource Description &Access metadata rules which are not tied to aprogramming language such as MARC but can workwith semantic web standards like XML); IRs, andCMS like Drupal which have semantic webcapabilities• RDA expressed as RDFaDraft Content for Discussion group 04.30.2013
  • 6. • What is linked data and open datao Linked data is about reusing datao We already do some linked data in our library catalogsand 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 that canthen be utilized in some way• Open data is data that available to be used in someway with no barriers to access (licensing, etc.)Draft Content for Discussion group 04.30.2013
  • 7. The RDF Triple:conceptual Examplessame asauthor ofPredicate/verbDraft Content for Discussion group 04.30.2013
  • 8. 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 IdentifierDraft Content for Discussion group 04.30.2013
  • 9. 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 linkeddata, and OCLC has a modified version of LCSH calledFAST as linked data• Linked Data is flexible enough to express entity-relationship relationships such as FRBR/FRAD• Different databases (ILS, ERMS, IRs, localdatabases, etc.) allowing sharing of data – potentiallymore consistent data – allowing for collocation acrossresources and allowing users to easily find resourcesregardless of sourceDraft Content for Discussion group 04.30.2013
  • 10. Our data in a semantic viewSOURCE: Getting triples from records: the role of ISBDhttp://www.slideshare.net/scottishlibraries/isbd-record2triples“Bib”:Recordid assubjectField role andrelationshipCan map to recordsuch as viafDraft Content for Discussion group 04.30.2013
  • 11. A changing library and WEB landscape• Automation and new technologies• The web has changed• Large scale bibliographic databases• Cooperative cataloging• Administrative desire to decrease costs• Greater variety of media in library collections(electronic!)• User expectations and needs• FRBR is our data model – semantic webfriendly!Draft Content for Discussion group 04.30.2013
  • 12. • Our future systems will most likely not use MARC, buta semantic web friendly schema.• Currently, the Library of Congress has started aproject called the Bibliographic FrameworkTransition Initiative• Why?• We need something that is more flexible, not flatin file structure, yet works with a semanticframework.• We need something that works better withdifferent metadata schemas.• This new framework will provide us with enormousfunctionality in our catalogs and allow us to fully useRDA. It will allow us to move forward into thesemantic web world.RDA, FRBR, and MARCDraft Content for Discussion group 04.30.2013
  • 13. Discussion points• How will using linked data change ourworkflows, and how will this challenge us?• Who will be responsible for maintaining theprovenance of information?• How will linked data be graphed? Will astandard bearer like OCLC or LC provide this,or will this be something that libraries willprovide?Draft Content for Discussion group 04.30.2013
