New functions of CiNii Articles: supporting JSON-LD format and cross-domain asynchronous communication by API, displaying the link to Information Processing Society of Japan.

October 29, 2013

The following new functions are available on CiNii Articles from Oct. 29 (Tue.).

1. API now supports JSON-LD

JSON-LD API (Beta ver.) for CiNii Articles is now available as well as CiNii Books 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). (*For JSON-LD API for CiNii Books, please see "New functions of CiNii Books: description and contents search, displaying author name transcription, supporting JSON-LD format and cross-domain asynchronous communication by API. (Oct 18, 2013)")

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

How to get RDF response in JSON-LD format

  • Append ".json" to the end of the CiNii Articles URL and send a request.
  • JSON-LD is supported by APIs of CiNii Articles RDF for "Articles" and "Authors".
  • Query example: Request to acquire the information on the Article "Activities to realize open government with linked open data" in JSON-LD format. -> http://ci.nii.ac.jp/naid/110007891128.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 JSON-LD specification update or user opinions.

About details of JSON-LD, see the following Page

2. API now supports cross-domain asynchronous communication

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

3. Displaying the link to Information Processing Society of Japan

The Link from CiNii to Information Processing Society of Japan is now displayed on the CiNii Articles search results page and details page. Also, part of character strings of other links have been changed.
