DESCRIPTIONPresentation of the Library Linked Data incubator group at W3C: http://www.w3.org/2005/Incubator/lld/
- 1. W3C Library Linked Data Incubator GroupAntoine Isaac Vrije Universiteit Amsterdam Europeana Talis Open Day: Linked Data and Libraries, London, July 21st 2010

- Library of Congress vocabularies, including LCSH
- DNBs Gemeinsame Normdatei
- BnFs RAMEAU subject headings
- OCLCs DDC classification and VIAF
- NL of Hungarys catalogue and thesauri
- Also relevant!
- STW economy thesaurus
- Social Science thesaurus
- GEMET environmental thesaurus
- New York Times subject headings
- Scientific publications

[Ross Singer, Code4Lib2010] http://code4lib.org/conference/2010/singer 5. Useful tooling
- Dublin Core
- In progress
- RDA vocabularies

- 2010, Year 1 of library linked data?
7. Libraries and LD, the perfect match?
- Libraries have been producing metadatafor ages
- Libraries (often) producehigh-qualitymetadata
8. Libraries and LD, the perfect match?
- Library metadata is stilllockedin records
- While it does maintain links to the outside world
- Bibliographic and web references
- Shared vocabularies
- Same books!
9. Unleash library data! 10. Johan Stapel, Koninklijke Bibliotheek A dream at the Dutch National Library 11.
- But there are obstacles
12. Emerging best practices?
- What vocabularies are being used, and is there emerging consensus about which to use?
- What licenses (if any) are associated with the data?
- How much linking and interlinking is going on?
- What sorts of mechanisms does the publisher offer for getting the data: sitemap, feeds, SPARQL, bulk download?
- What is the quality of the data: granularity, link integrity, vocabulary usage.
- What approaches to identifiers for real world things have publishers taken: hash, slash, 303, PURLs, reuse of traditional identifiers, etc.
- What are the relative sizes of the pools of library linked data?
- How are updates being managed?
Ed Summers http://inkdroid.org/journal/2010/04/18/research-ideas-for-library-linked-data/ 13. Connecting to more general LD Issues
- Mike Uscholds semantic elephants
- Proliferation of URIs, Managing Coreference
- Overloading owl:sameAs
- Versioning and URIs
http://lists.w3.org/Archives/Public/public-lod/2010May/0012.html 14. Also, gospel is needed 15. Whats this I hear about theSemantic Web ?
- 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?
http://www.slideshare.net/stuartweibel/semantic-web-technologies-changing-bibliographic-descriptions 16. Determine use case & business models
- Libraries may just publish data, but they can do more
- Connect library data to other data
- Integrate data from external sources in library systems
- Potential data consumers deserve some help, too
17. Linking strategy
- Links to library-originated sources
- VIAF, LCSH, DDC, UDC
- RDA vocabularies
- Worldcat, TEL
- Links to resources from the natural environment
- Museums, archives
- Scientific communities: bibliographic data & research data
- Europeana and other aggregators
18. Need for charting the LLD landscape 19. W3C incubator (XG) activity
- Short-lived working groups: 1 year
- Light administration burden
- NotW3C Recommendations, but innovative ideas for specifications, guidelines, and applications that are not (or not yet) clear candidates as Web standards
- Deliverables are, but XGs can trigger further W3C work
http://www.w3.org/2005/Incubator/ 20. Example XGs
- Multimedia semantics
- Social Web
21. LLD Steps
- Preparing a charter
- Initial chairs: Tom Baker, Emmanuelle Berms, Antoine Isaac
- 10 W3C initiating members
- Aalto University Helsinki
- DERI Galway
- Competence Centre for Interoperable Metadata (KIM)
- Library of Congress
- Los Alamos National Laboratory
- University of Applied Sciences Potsdam
- Vrije Universiteit Amsterdam
- Tohelpincrease global interoperability of library data on the Web, by
- bringing together peopleinvolved in Semantic Webactivities focusing on Linked Datain the library community and beyond,
- building on existing initiatives , and
- identifying collaboration tracks for the future .
http://www.w3.org/2005/Incubator/lld/charter 24. Activities
- Gathering use cases and case studies demonstrating successful implementation of Semantic Web technologies in libraries and related sectors
- Fostering collaboration among actors (libraries, museums, archives, publishers) interested in porting cultural assets to the Linked Data Web
- Identifying relevant data models, vocabularies and ontologies and ways to build or improve interoperability among them
- Identifying the need for the elaboration of new standards, guidelines & best practices
- Identifying the areas of (Semantic) Web technology that could benefit from the expertise of the communities represented in the Group
- Proposing a relevant scope and organization for work that follows on the initial effort carried by the Group.
http://www.w3.org/2005/Incubator/lld/charter 25. Planned deliverables
- Report presenting the landscape of Linked data development in the library domain and related sectors, including:
- Ause-case documentthat describes a number of real-world use cases, case studies, outreach and dissemination initiatives targeted to the library community and related sectors
- Adocument that describes relevant technology pieces , including vocabularies and ontologies (e.g., SKOS), with the intended goal to identify extension or interoperability requirements, and help determine what other standards may be needed.
http://www.w3.org/2005/Incubator/lld/charter 26. Charter leaving scope open
- The incubator group has been initiated by actors from national libraries, university libraries and research units, library vendors companies and other interested stakeholders. Its scope is howevernot limited to libraries as institutions , but is meant to involveother cultural heritage institutions , partners from thepublishing industry , andother relevant domains .
- Potential Links with other communities
- W3C eGovernment Interest Group
http://www.w3.org/2005/Incubator/lld/charter 27. Charter leaving scope open
- The Incubator could contribute feedback and ideas re. other W3C area
- Experience in modeling and publishing data
