Promises and Pitfalls: Linked Data, Privacy, and Library Catalogs

  1. 1. Promises and Pitfalls: Linked Data, Privacy, and Library Catalogs Emily Dust Nimsakont Cataloging Librarian, Nebraska Library Commission TSRT/IFRT Spring Meeting March 6, 2015
  2. 2. What is Linked Data? Photo credit: http://www.flickr.com/photos/mytudut/5197551003/
  3. 3. Wikipedia says… “Linked Data describes a method of publishing structured data, so that it can be interlinked and become more useful. It builds upon standard web technologies, such as HTTP and URIs - but rather than using them to serve web pages for human readers, it extends them to share information in a way that can be read automatically by computers.” http://en.wikipedia.org/wiki/Linked_Data
  4. 4. resource resource resource resource resource links to links to links to links to
  5. 5. data links to links to links to links to data data data data data data data data data data data
  6. 6. HTML <h1>This is a heading.</h1> <p>This is a paragraph.</p>
  7. 7. RDF/XML <rdf:Description rdf:about="http://www.recshop.fake/cd/Empi re Burlesque"> <cd:artist>Bob Dylan</cd:artist> <cd:country>USA</cd:country> <cd:company>Columbia</cd:company> <cd:price>10.90</cd:price> <cd:year>1985</cd:year> </rdf:Description> http://www.w3schools.com/rdf/rdf_example.asp
  8. 8. We are used to connecting pieces of information based on their context. Title: A Christmas Carol Author: Charles Dickens Relationships are key. Photo credit: http://www.flickr.com/photos/brenda-starr/3509344100/
  9. 9. Linked Data makes the relationships explicit (to computers!) subject object A Christmas Carol Charles Dickens has author predicate
  10. 10. <rdf:Description rdf:about="http://www.recshop.fake/cd/Empi re Burlesque"> <cd:artist>Bob Dylan</cd:artist> <cd:country>USA</cd:country> <cd:company>Columbia</cd:company> <cd:price>10.90</cd:price> <cd:year>1985</cd:year> </rdf:Description> http://www.w3schools.com/rdf/rdf_example.asp
  11. 11. “Just as the traditional document Web can be crawled by following hypertext links, the Web of Data can be crawled by following RDF links. Working on the crawled data, search engines can provide sophisticated query capabilities... Because the query results themselves are structured data, not just links to HTML pages, they can be immediately processed, thus enabling a new class of applications based on the Web of Data.” Chris Bizer, Richard Cyganiak, and Tom Heath How to Publish Linked Data on the Web http://linkeddata.org/docs/how-to-publish

  17. 17. Web Visibility “When my community searches the web for something we have, we better show up as an option.” Chuck Gibson, Director & CEO Worthington Public Library “The Visible Library,” Library Journal Webcast, February 26, 2015 http://goo.gl/8NErmA

  20. 20. Libraries and Privacy Photo credit: https://www.flickr.com/photos/pong/2404940312/
  21. 21. “Librarians feel a professional responsibility to protect the right to search for information free from surveillance. Privacy has long been the cornerstone of library services in America. Why? Because the freedom to read and receive ideas anonymously is at the heart of individual liberty in a democracy. Librarians defend that freedom every day. Libraries are information hubs for their communities. They are also natural centers for learning and talking about information issues… including privacy.” http://chooseprivacyweek.org/our-story/why-libraries/

  23. 23. “Libraries no longer own much of the content they provide to users; rather it is subscribed to from a variety of vendors. Not only does that mean that vendors will have to make their data available in linked data formats for improvements to federated search to happen, but a mix of licensed and free content in a linked data environment would be extremely difficult to manage.” Gillian Byrne and Lisa Goddard The Strongest Link: Libraries and Linked Data http://www.dlib.org/dlib/november10/byrne/11byrne.html
