CiNii Articles RDF for Articles Format Specification

When you access to the following URI, you can obtain the data with RDF/XML format. What information you can obtain is as the same as "CiNii Articles JSON-LD for Articles". "Article Information (Japanese)" and "Author Information" will be output.
https://ci.nii.ac.jp/naid/<naid>.rdf (For example: https://ci.nii.ac.jp/naid/110009544496.rdf)

Content Negotiation is also acceptable. Even if RDF URI is not be specified, RDF will respond by recognition from HTTP header. In the Article Details Page (For example:https://ci.nii.ac.jp/naid/110009544496)), specification of "application/rdf+xml" in Accept field of HTTP request header has much priority than any other specifications, it will induce automatically to RDF URI.

"Access-Control-Allow-Origin*" is required on http header for response, and it is available to use asynchronous communication between cross domains.
