Application Programming Interface (API)

1. API supported by the National Diet Library Great East Japan Earthquake Archive (HINAGIKU)

HINAGIKU supports both search API and harvest API. Metadata from all data providers in the "List of Data Providers and Available Metadata" can be acquired by either API.
Please read the "About API use application" page before using API. If you wish to use API from a service other than HINAGIKU, please see the "List of API" page on the National Diet Library website.

1.1. Search API

You can search HINAGIKU metadata using the search API. The available search conditions will vary depending on the API protocol used.
The search API is compliant with SRU and OpenSearch.
You can make search windows by incorporating the search API.

1.2. Harvest API

You can download HINAGIKU metadata using the harvest API, which is made available by OAI-PMH.
Metadata downloaded from HINAGIKU can be imported to other systems.
※The harvest API uses some cache functions, which could affect response, depending on conditions and timing of the request.


The details of each API are as follows.

2. Data available via API

2.1. Available data

Only metadata is available.

2.2. Metadata formats

Metadata of HINAGIKU is compliant with "The National Diet Library Great East Japan Earthquake Archive Metadata Schema", which is based on The National Diet Library Dublin Core Metadata Description (DC-NDL).
Format of data returned by each protocol is also based on "The National Diet Library Great East Japan Earthquake Archive Metadata Schema".

2.3. Metadata updates

Metadata is not updated in real time. Rather, batch processing is carried out daily.
If you search or harvest metadata by API around midnight Japan Standard Time, the metadata you receive might not be the latest version.

2.4. List of Data Providers and Available Metadata

For either search API or harvest API, you can narrow the range of search objects by specifying a Repository ID for the following Data Providers.
For the outlines of each Repository, please see the page "The list of searchable databases and others".
