3. Textbook LOD’s URI (IRI) enables to
   uniquely identify a textbook in Japan
   • Example of a URI (IRI):
   3
   https://w3id.org/jp-textbook//2006/B/013
   "World History B" textbook used in upper secondary school and authorized in 2006
   Type of school, year of authorization, textbook symbol, and textbook number
   are described in the textbook.
   Textbook symbol and textbook number are maintained by the Ministry of Education.

5. Publishing/Hosting Textbook LOD
   • Publication Methods
   • Permanent URI service operated by the World Wide Web
   Consortium Permanent Identifier Community Group
   • Github pages
   • Providing Contents
   1. Downloadable files for the datasets as a format of
   RDF/Turtle
   2. Useful information through its URIs
   1. A human-friendly web page
   2. A machine-readable format
   3. Several useful links to lists of subject areas and subjects
   4. Detailed documentation about the dataset including its
   metadata model and revision history
   5
   It’s free for use and easy to use.
   The actual website for Textbook LOD
   can be changed, so we use the
   service for Permanent URI.

    Bibliographic data for
    textbooks is maintained by
    the library.
    If we found errors in the data in
    the making LOD process, we
    notified ones the library.
    Created by only with MS Excel,
    MS Word and a text editor*

13. Conclusion
    • We introduce a case study for publishing a small
    bibliographic collection as LOD.
    • We provide the Japanese textbook resources as LOD.
    • Using Textbook LOD’s URI (IRI), it has became possible
    to point to Japanese textbooks uniquely.
    • We collaborate with the library for development and
    publication of the dataset.
    • The dataset is freely available under the CC0 (Creative
    Commons Zero) license.
    • Please visit the Textbook LOD Web site!
