CiNii Research RDF Format Specification
You can obtain data in RDF/XML format by accessing the URI in the following format.
https://cir.nii.ac.jp/crid/<crid>.rdf （example：https://cir.nii.ac.jp/crid/1420564276161825792.rdf）
It supports content negotiation, and returns RDF based on the HTTP header even if the RDF URI is not specified. In the details display screen (e.g. https://cir.nii.ac.jp/crid/1420564276161825792), it directs to the URI of RDF if the specification of "application/rdf+xml" in the Accept field of the HTTP request header has a higher priority than any other specification.
