  • 9. How can we make information open and shared? Share Collect Publish Use & Create Hideaki Takeda / National Institute of Informatics
  • 10. Linked Data Linked Data is “Web of Data” Standard format  Data published as RDF Linkable to each other!  Can refer from outside Four conditions for Linked Data  Use URIs as names for things  Use HTTP URIs (http://..) so that people can look up those names.  When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL)  Include links to other URIs. so that they can discover more things.Linked Data, TBL, http://www.w3.org/DesignIssues/LinkedData.html Hideaki Takeda / National Institute of Informatics
