3. API now supports JSON-LD

JSON-LD API (Beta ver.) for CiNii Books is now available in addition to OpenSearch(RSS1.0, Atom1.0) and RDF which are already provided. JSON-LD is a specification which expresses Linked Data in JSON format and currently under development by the W3C (World Wide Web Consortium).

This API is based on the specification as of September 10, 2013 "JSON-LD 1.0 A JSON-based Serialization for Linked Data W3C Candidate Recommendation 10 September 2013".

The query and response specification are compatible with OpenSearch and RDF. You can get JSON-LD data by specifying JSON as response format.

How to get OpenSearch response in JSON-LD format

• Send a parameter "format" in the request with a value of "json".
• JSON-LD is supported by All APIs of CiNii Books OpenSearch for "Books & Journals", "Authors", "Libraries" and "Holdings".
• Query example : Request for search results of the books and journals containing "informatics" in the title in JSON-LD format. -> http://ci.nii.ac.jp/books/opensearch/search?title=%22%E6%83%85%E5%A0%B1%E5%AD%A6%22&format=json

How to get RDF response in JSON-LD format

• Append ".json" to the end of the CiNii Books URL and send a request.
• JSON-LD is supported by All APIs of CiNii Books RDF for "Books & Journals", "Authors" and "Libraries".
• Query example: Request to acquire the information on the book "Linked Data : Webをグローバルなデータ空間にする仕組み" in JSON-LD format. -> http://ci.nii.ac.jp/ncid/BB11534438.json

*Application consideration

• Details page about the request and response specification of JSON-LD API(Beta ver.) is now in preparation. Thank you for your patience.
• Please be advised that the request and response specification of "Beta ver." may be subject to change by update JSON-LD specification or user opinions.

4. API now supports cross-domain asynchronous communication

Each CiNii Books API now supports cross-domain asynchronous communication by appending "Access-Control-Allow-Origin: *" to the http response request header.
