    W3C Library Linked Data Incubator Group  - 2011 W3C Library Linked Data Incubator Group - 2011 Presentation Transcript

    • W3C Library Linked Data Group A Summary Antoine Isaac Europeana Vrije Universiteit Amsterdam Talis Linked Data and Libraries day, London, July 14th 2011
    • ?
    • W3C incubator (XG) activity
      • Short-lived working groups: around 1 year
      • No delivery of W3C Recommendations, but “innovative ideas for specifications, guidelines, and applications that are not (or not yet) clear candidates as Web standards”
    • Library Linked Data incubator
      • May 2010 – August 2011
      • 51 participants
      • 23 W3C member organizations
        • VU Amsterdam, INRIA, Library of Congress, JISC, Deutsche Nationalbibliotek, DERI Galway, OCLC, Talis, LANL, Helsinki University of Technology, University of Edinburgh, etc.
      • Invited experts from other organizations
        • BnF, National Library of Latvia, German National Library of Economics, etc.
        • Up-to-date list at http://www.w3.org/2000/09/dbwg/details?group=44833
      • To help increase global interoperability of library data on the Web, by
      • bringing together people involved in Semantic Web activities —focusing on Linked Data—in the library community and beyond,
      • building on existing initiatives , and
      • identifying collaboration tracks for the future .
    • Linked Library Cloud 2008 [Ross Singer, Code4Lib2010] http://code4lib.org/conference/2010/singer
    • 2010 [Ross Singer, Code4Lib2010] http://code4lib.org/conference/2010/singer

      • What is the Semantic Web?
      • What does it have to do with bibliography?
      • Does it make life better for patrons?
      • Does it strengthen libraries?
      • Is it practical?
      • Where can we get some?

      • (Europeana links give access to resources on original sites, with copyright info)
    • General benefits of linked data
      • Shareable
        • Globally unique resolvable identifiers - URI
        • Libraries can make trusted metadata descriptions for common use
      • Extensible
        • "Open world" - no description is complete, anybody can add descriptive information from within their own publishing space
      • Re-usable
        • Descriptions from diverse sources talking about the same thing
        • Annotations, enrichments, etc.
      • Internationalisable
        • Full support for translations of terms to other languages
        • Natural language strings are not used as identifiers
    • Benefits to researchers, students and patrons
      • Greater discovery and use capabilities, across library and non-library resources, across disciplines
      • Information seekers can extract and re-mix the parts of the data they need, add own annotations to library global graph
      • Semantics in HTML allow resources to be better discovered from websites they use routinely
      • Library items and data can be fully integrated into research documents and bibliographies
    • Benefits to cultural institutions
      • Use of mainstream technologies rather than formats and integrated systems specific to libraries
      • Sharing data, particularly for items/works and authority data, means less duplication of effort, lower infrastructure costs
      • Clarification of metadata licensing
      • Greater visibility on the web and reuse
    • Benefits to librarians, archivists and curators
      • Use of web-based identifiers makes resources immediately available and up-to-date
      • Pull together data from outside their domain environment
        • across cultural heritage datasets
        • from the web at large
      • Concentrate on their domain of local expertise rather than re-creating existing descriptions
    • Benefits to developers
      • Use of well known standard protocols and techniques instead of domain-specific software
        • HTTP instead of Z39.50
        • RDF instead of MARC or EAD
        • REST
      • Freely mix or mash-up data from libraries with other sources
    • Challenges and barriers
      • Designed for stability, the library ecosystem resists (technological) change
      • Tendency to engage only with well-established standards and practices
      • Standardization processes are long-term, top-down
        • Bottom-up can be successful but garner little recognition
      • Tech. expertise lies mostly with a small number of software vendors or in large academic libraries
        • Libraries are Libraries are understaffed in the technology area
    • Challenges and barriers
      • Sharing of data traditionally happens amongst libraries, not with the wider world
          • There is fear that data will need to be "dumbed down" in order to interact with other communities; few see the possibility of "smarting up” data
      • Cooperative metadata creation is economical but centralised
    • Challenges and barriers
      • ROI is difficult to calculate
      • Cost of current practice is not well known
      • LD requires tech. staff with specific expertise in library data
      • Library-specific data formats require niche systems solutions
    • Challenges and barriers
      • Data may have rights issues that prevent (open) publication
      • Some data cannot be opened
      • Rights have perceived value
      • Ownership of rights can be unmanageably complex
    • Challenges and barriers
      • Data in library-specific formats is not easily shared outside the library community
      • Data is expressed primarily as text strings, not "linkable" URIs
      • Self-contained records differ from open-world graphs
      • Best practices or standardisation for using RDF with library data are needed
      • The library and LD communities lack shared terminology for metadata concepts
        • statement, heading, authority control
    • Recommendations
      • Assess
      • Identify candidate datasets for early exposure as linked data
      • For each dataset, determine ROI of current practices, and costs and ROI of exposing as LD
      • Evaluate migration strategies
      • Foster a discussion about open data and rights
    • Recommendations
      • Facilitate
      • Cultivate an ethos of innovation
        • Small scale R&D within individual library organisations
      • Identify Linked Data literacy needed for different staff roles in the library
      • Include metadata design in library and information science education
      • Increase participation in linked-data standardisation efforts
    • Recommendations
      • Design and prepare
      • Translate library data and standards into linked data
      • Develop best practices and design patterns for data
      • Directly use or map to commonly understood LD vocabularies
      • Design user stories and exemplar UIs
      • Identify tools supporting the creation and use of LLD
    • Recommendations
      • Curate, identify and link
      • Apply library experience in curation and long-term preservation to linked data (and other) datasets
      • Ensure preservation of relevant linked data vocabularies
      • Assign unique identifiers (URIs) for all significant things in library data
      • Create explicit links between library datasets and to other well-used datasets
