The document discusses the establishment and goals of the W3C Library Linked Data Incubator Group, which aims to increase interoperability of library data on the web through linked data. It highlights existing implementations and best practices, the challenges of integrating library data into the semantic web, and proposes future activities including gathering use cases and fostering collaboration among libraries and other cultural institutions. The group encourages participation from a variety of stakeholders and aims to provide resources and guidelines to enhance the use of linked data in libraries.

6. 2010, Year 1 of library linked data?

7. Libraries and LD, the perfect match? Libraries have been producing metadata for ages Libraries (often) produce high-quality metadata

8. Libraries and LD, the perfect match? Library metadata is still locked in 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/

14. Also, gospel is needed

15. What’s this I hear about the Semantic 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 Crowdsourcing? 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 Publishers 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 Not W3C 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 Provenance Multimedia semantics Social Web …

LLD Steps Preparing a charter Initial chairs: Tom Baker, Emmanuelle Bermès, Antoine Isaac 10 W3C initiating members Aalto University Helsinki DERI Galway Competence Centre for Interoperable Metadata (KIM) Library of Congress Los Alamos National Laboratory MIMOS OCLC Talis University of Applied Sciences Potsdam Vrije Universiteit Amsterdam

23. 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 . 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: A use-case document that describes a number of real-world use cases, case studies, outreach and dissemination initiatives targeted to the library community and related sectors A document 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 however not limited to libraries as institutions , but is meant to involve other cultural heritage institutions , partners from the publishing industry , and other relevant domains .
