Enhancing Dewey Summaries with Multilingual Linked Data Principles

This summary discusses the application of Linked Data principles to Dewey Summaries, emphasizing the use of HTTP URIs for identification, providing dereferenceable information, and establishing relationships between data entities. It outlines key requirements for publishing Linked Data, such as unique identification via URIs and adherence to formats like RDF for machine readability and HTML for human comprehension. The document illustrates use cases for linking data, showcasing how external summaries can be accessible in multiple languages. A collaborative approach invites suggestions for further use cases.

  1. Dewey Summaries as Multilingual Linked Data • Dewey Breakfast/Update • ALA Annual • July 11, 2009

  2. Linked Data principles • Three rules • Use http-URIs as names for things (identification) • When someone looks up a URI, provide useful information (dereferenceability) • Include links to other URIs (relationships) • Maxims • “Raw data now!” (TBL) • Being able to ask new question about data • Adding information collaboratively

  3. Linked Open Data cloud

  4. Requirements for publishing Linked Data • Identification • Every data entity has a URI • Access • HTTP as protocol (established infrastructure: WWW) • User agent indicates which data formats it accepts • Representation • for machines • RDF as data model • SKOS, Dublin Core, ccREL, etc. as vocabularies • for humans • HTML, etc. • “Openness” of the data set

  5. Use Cases: Basic web lookup • “If someone has the URI of that thing, what relationships to what other objects is it useful to know about?”(Tim Berners-Lee) • A web page for every class of the Dewey Summaries, e.g.: • <http://dewey.info/class/641/>

  6. Use Cases: Basic linking • Example: Dublin Core metadata • <dc:title>Petrology.</dc:title><dc:creator>Huang, Walter Ta, 1924-</dc:creator><dc:subject xsi:type="http://purl.org/dc/terms/DDC">552</dc:subject> • Use of a link (URI) instead of arbitrary text

  7. Use Cases: Basic linking • Example: Dublin Core metadata • <dc:title>Petrology.</dc:title><dc:creator>Huang, Walter Ta, 1924-</dc:creator><dc:subject rdf:resource="http://dewey.info/class/552/e16/" /> • Use of a link (URI) instead of arbitrary text

  8. Service: Dewey Summaries as Linked Data • External summaries of DDC 22 • Main Classes, Divisions, Sections • Accessible • as RDF data or HTML web pages • in 9 languages • Reusable • by anyone • under terms of Creative Commons BY-NC-ND 3.0 license

  9. Demo: Dewey Summaries as Linked Data • http://dewey.info/class/641/ • http://dewey.info/class/641/about.rdf • http://dewey.info/class/641/about.en • http://dewey.info/class/641/about.sv • http://dewey.info/class/641/2009/06/about.ar.html • http://dewey.info/class/641/2009/01/about.ar.rdf
