About RDF
With the CiNii it is possible to output contents of the authors details page with RDF(*). Here, we will explain the format specifications of RDF.
*RDF stands for Resource Description Framework. For more information please refer to the following site.
http://www.w3.org/RDF/
With RDF, CiNii's data can be utilized in various ways since each data item, like author name, is structured in a standardized way using metadata descriptors such as FOAF, etc. and is output with XML.
A Authors details page output with RDF.
- Display the details page.

- Add ".rdf" to the URL in the address bar. Even when the RDF URL is input directly, the same results are displayed because the RDF URL becomes "details page URL"
Example: http://ci.nii.ac.jp/nrid/1000080143551 => http://ci.nii.ac.jp/nrid/1000080143551.rdf
- The content of the details page is output with RDF.
