CiNii Books JSON-LD for Books & Journals Format Specification

Note: This is a Beta version therefore Format Specification may be subject to change hereafter depending on user feedbacks. Please be advised before using.

When you access to the following URI, you can obtain the data with JSON-LD format. What information you can obtain is as the same as "“CiNii Books RDF for Books & Journals". Books Format and Journals Format are different.
https://ci.nii.ac.jp/ncid/<ncid>.json（Example: https://ci.nii.ac.jp/ncid/BB08796640.json）

Content Negotiation is also acceptable. Even if JSON-LD URI is not be specified, JSON-LD will respond by recognition from HTTP header. In the Books & Journals Details Page (For example : https://ci.nii.ac.jp/ncid/BB08796640), specification of "application/json" or "application/ld+json" in accept field of HTTP request header has much priority than any other specifications, it will induce automatically to URI of JSON-LD.

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