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
- Send a parameter "format" in the request with a value of "json".
- JSON-LD is supported by All APIs of CiNii Articles OpenSearch for "Articles", "Authors", and "Full text".
- Query example : Request for search results of articles containing "informatics" in the title in JSON-LD format. -> http://ci.nii.ac.jp/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 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.

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.
