Are Libraries Ready for Linked Data?

3,704

Published on

From Legacy Data to Linked Data: Preparing Libraries for Web 3.0. Presented at ALA Annual, Monday, June 13th, 8:00-10:00 AM

Session blurb: "How can library cataloging data be transformed to function within “Web 3.0” and be understood by non-library web applications? Speakers from both the library and Semantic Web communities will explore the situation in a non-technical manner and describe current work underway to transform legacy library data into linked data.

  • In general the record identifies the object, or, its description as a whole is adequate to identify the object.
  • Are Libraries Ready for Linked Data?

    1. 1. Are Libraries Ready for Linked Data?<br />A not-too-technical look at the question at hand …<br />Diane I. Hillmann<br />Information Institute of Syracuse/<br />Metadata Management Associates<br />
    2. 2. To Re-phrase the question …<br />If “linked data” is about relationships …<br />And we’re done (pretty much) with expressing relationships using textual notes (as we have done for decades—nay, CENTURIES—first on catalog cards, then using AACR and MARC)<br />And we understand that we need machine-based methods to really do the job well … THEN …<br />7/13/09<br />2<br />ALA Annual: Linked Data Program<br />
    3. 3. We’re READY!<br />7/13/09<br />3<br />ALA Annual: Linked Data Program<br />
    4. 4. Getting Real--Defining READY<br />Availability of schemas and vocabularies<br />RDA is full of relationships, from the FRBR model to the extensive relationship vocabularies currently registered and near completion<br />Availability of applications and tools that can help us use linked data<br />Started, certainly, but not entirely there yet<br />[Jennifer will talk a bit about this part]<br />7/13/09<br />4<br />ALA Annual: Linked Data Program<br />

    6. 6. What’s All This About Triples?<br />In traditional cataloging, you get attribute/value pairs:<br /> Title = Bluebeard<br /> Author = Vonnegut, Kurt<br />And you know what the object of the statements are because they’re part of a RECORD<br />7/13/09<br />6<br />ALA Annual: Linked Data Program<br />
    7. 7. What’s All This About Triples?<br />In traditional cataloging, you get a record package, with an ID:<br /> Title = Bluebeard<br /> Author = Vonnegut, Kurt<br />The record is identifiable and shareable, but the statements within that package cannot stand alone<br />Record ID=abc12345<br />7/13/09<br />7<br />ALA Annual: Linked Data Program<br />

    11. 11. Q: How do we make Identifiers for Relationships?A: We already have them, in RDA<br />7/13/09<br />11<br />ALA Annual: Linked Data Program<br />

    18. 18. Please Note:<br />The fact that the registration of RDA vocabularies supports a linked data future for libraries is NOT ACCIDENTAL<br />We owe a great deal to the funders of the DCMI/RDA Task Group (The British Library and Siderean Software), who had the vision to wade in and support this work<br />The vocabularies will be complete, reviewed and with status “published” when RDA is released<br />7/13/09<br />18<br />ALA Annual: Linked Data Program<br />
