    • 1. Establishing the Connection: Creating the Linked Open British National Bibliography Neil Wilson Head of Metadata Services Online Information Conference 30 November 2011!/BLMetadata
    • 2. British Library Metadata Services Background
      • Operated prior to the BL’s foundation as ‘The British National Bibliography’ (BNB) Ltd from1950
      • Originally offered priced services for national & international libraries
      • Evolved through changes in format & delivery technologies
      • Offered free services from 2010 as part of the BL’s new open metadata strategy
    • 3. BL Metadata Services Stakeholder Relationships
    • 4. Library Sector Relevance? Declining? Increasing?
      • “ I did my PhD with only 12 visits to a library. That was 5 years ago; things have improved since then, now you don’t need to use one at all!”
      • “ The release of library data offers the opportunity for it to be used in ways unthought-of by the library & information community…”
    • 5. Changing Expectations Putting Public Sector Data To Work
      • McKinsey forecasts the benefits value of open public data could be 250bn Euros
      • “ Putting the Frontline First ” required “ the majority of government-published information to be reusable, linked data” by June 2011 .
      • Public data will be released under the same open licence which enables free re-use, including commercial re-use
    • 6. Library Metadata The Promise of Linked Data
      • Better web integration of resources increasing visibility & reaching new users
      • A global pool of reusable data for organisations to add unique value
      • New library leadership opportunities due to persistence, stability & authority
      • Such benefits cross national & sectoral boundaries but require huge cultural changes
    • 7. How Are We Meeting The Challenge?
      • Our new open metadata strategy aims to:
      • Enable increased innovation without unnecessary barriers
      • Break from library formats & use cross domain standards
      • Obtain attribution while offering more permissive licensing
      • Deliver with decreasing resources while maintaining revenue
    • 8. What Have We Achieved?
      • Signed over 450 organisations in 71 countries to free data services
      • Supplied 3-15 million item XML datasets under Creative Commons licenses
      • Worked with JISC & linked open data implementers on technical, standards & licensing challenges
      • Created a linked data version of the British National Bibliography
    • 9. Our Linked Data Journey… Why the British National Bibliography?
      • We wanted to:
      • Advance debate from theory to practice via release of a critical mass of data
      • Show commitment by using a core dataset - niche examples are not as compelling
      • Create a foundational service others can build upon & not a dead end
    • 10. Our Linked Data Journey… Preliminaries
          • We first identified:
          • The best licensing model for our objectives (CC0)
          • A proven hosting platform (Talis)
          • Sources of expert knowledge & feedback (e.g. W3C, Open Bibliography etc)
      • … in order to concentrate effort on adding new value to our data
    • 11. Our Linked Data Journey… Additional Objectives
      • The project would be a staff & organisational development opportunity using:
          • In-house personnel i.e. librarians rather than IT experts
          • Pre-existing tools & technologies
          • Library MARC21 data
          • Established & trusted linked resources
    • 12. Our Linked Data Journey… Migrating From a Flat Catalogue Card Model…
      • We aimed to:
      • Start simple & develop in line with evolving staff expertise
      • Utilise staff training & mentoring from Talis in:
            • Linked data concepts
            • RDF modelling
            • Presentation options
      • … and use the opportunity to blend the best of traditional & new approaches
    • 13. Our Linked Data Journey… To Something New…
    • 14. Our Linked Data Journey… Selecting Sites To Link To (for mutual benefit)
      • To position our data in a wider context
      • We blended general linked resources i.e.:
              • GeoNames
              • Lexvo
              • RDF Book Mashup
      • With key linked library resources i.e.:
              • LCSH SKOS
              • VIAF
    • 15. Our Linked Data Journey… Matching & Generating Links
      • Three approaches used:
      • Automatic generation from data elements in records
      • Automated text matching with linked data resource dumps
      • Two stage crosswalk matching process for coded data
    • 16. Our Linked Data Journey… Embedding The Links
    • 17. Our Linked Data Journey The MARC to RDF XML Conversion Workflow MARC to RDF XML Conversion Consists of multiple automated steps using a number of tools
      • Selection
      • Pre-processing
      • Character set conversion
      • URI Generation
      • Data Transformation
    • 18. Where Did We Get To? Hosted on the Platform: . BNB Books 1950-2011 2.5 Million Records 80 Million Unique RDF Triples
    • 19. What Does It Look Like ?
    • 20. Lessons Learned - Its a new way of thinking…
      • Legacy data wasn’t designed for this so take care with data modelling & sustainability
      • Everyone is still learning so you may be the best judge
      • There are often tools or expertise out there so don’t reinvent the wheel
    • 21. Lessons Learned – Data Issues
      • Offer sample access to the community for feedback
      • Expect criticism in addition to positive feedback & continually improve
      • Any conversion inevitably identifies hidden data issues…& creates new ones!
      • … but it’s often better to release an imperfect something than a perfect nothing!
    • 22. Lessons Learned - Staff and Resource Issues
      • It can be a steep learning curve so:
      • Exploit external expertise to work with or guide your own domain experts
      • Cultivate a staff culture of enquiry & innovation to widen perspectives
      • Identify & use pre-existing tools to save development time & assist data validation
    • 23. Lessons Learned – Was It Worth It?
      • The benefits have been significant & the initiative has:
          • Given us a presence without distorting revenue streams …& may even offer new options
          • Gained us a 1 st mover advantage within our sector & advanced discussion as hoped
          • Shown that if you offer useful data, people will use it With over 3 million transactions in the 1 st 3 months
    • 24. Our Linked Data Journey - Where Next?
          • Release of further BNB material
          • Refine & document the new data model
          • Identify further resources to link to
          • Monthly updates on completion
          • Identify what else can be offered?
    • 25. Final Thoughts…
      • It’s never going to be perfect first time
      • We expect to make mistakes
      • We aim to learn from them
      • We hope others will learn something too
      • & everyone benefits
      • So if anyone is thinking of undertaking a similar journey…
      • Just do it!
