Unlocking doors: recent initiatives in open and linked data at National Library of Scotland

  1. 1. unlocking doorsrecent initiatives in open and linked data at National Library of Scotland Gill Hamilton Digital Access Manager g.hamilton@nls.uk
  2. 2. about
  3. 3. widening access to knowledge"we will make digital resources accessible through communications media which are effective in promoting the use and discovery of our collections."
  4. 4. widening access to knowledge"we will improve access to our collections by finding new ways for our users to interact with us and others."
  5. 5. social media servicesFlickr www.flickr.com/photos/nlscotland • 2,500 images • 1,500 views per day • 1.8 million views in total • 10% have comments
  6. 6. social media servicesFlickr 52,000 views 114 favorited 20 comments "It is a Lee Enfield gun .." "Im doing a presentation, may I use the image?"http://www.flickr.com/photos/nlscotland/3012796098/
  7. 7. social media servicesYou Tube 102 videos 300,000 views 186 comments "Fab wee motor." "My parents had onehttp://www.youtube.com/watch?v=Z9l01vy7y3w of these"
  8. 8. social media servicesLicensing, copyright and rights• out of copyright and/or copyright owner• to gain benefits you must give away some or all control• Flickr The Commons
  9. 9. social media servicesLessons learned....• minimal investment for improved access• taster of the Librarys collections• the world is full of knowledgeable people• to gain benefits you have to give something up• findability beyond the Library website• open ... but not open enough
  10. 10. open datais the concept that data is made available so others can use and re-use it without restrictions of copyright or control mechanisms
  11. 11. open dataif you created the metadata then you can license it as you wishif you create or own the resource then you can license it as you wish
  12. 12. open stuff we’ve been doing CC.0
  13. 13. open dataThe 5 easy steps to open data 1. licensed 2. structured 3. documented 4. published 5. publicised "Give us raw data and give it to us NOW!"
  14. 14. open data http://thedatahub.org/dataset/nls-forthbridge
  15. 15. linked open data and usWhat we dont have .... experience skills resourcesWhat we do have ... great data lots of enthusiasm friends to help
  16. 16. linked open dataWhat we did until April 2012stop ... start ... stop ... start ... stop ... start • went to school to learn RDF • tried mapping our data to DC Terms • tried to discover URIs • created RDF for a single resource • wondered what to do next • wondered if it was worth our while
  17. 17. linked open dataAnd then we spoke to our friends:freeYourMetadata.org "you should use Google Refine to discover URIs"Open Knowledge Foundation "use theDataHub.org for publishing & use CC.0"Metadata Management Associates "let us help you model your data because we have a theory ..."

  31. 31. finding things from strings• By hand by Gill• By the hands of students• By Google Refine• By some clever algorithmic cleverness
  32. 32. where are we right now?• PHP script that makes TTL triples• a triple store• the crudest interface in the world ALL ON A LAPTOP• basic linking outside the NLS domain• a workshop on Wednesday
  33. 33. where are we right now?
  34. 34. where are we right now?
  35. 35. linked open data• think about URIs• think about infrastructure• think about the vocabularies we use• publish Forth & Haig as DOD LOD• try to link internally• Haig and• WWI (Zeppelin?) maps• and diaries• perhaps build a service
