RADAR API

Erste Schritte zur Nutzung des RADAR API

Before you start

Before you start to use (or test) our RADAR API please: 

  1. Contact us for activating an OAuth ClientID. This client gives you permission to communicate with the RADAR backend authorization service.
  2. In case you use RADAR with Shibboleth accounts: Please take note, that no Shibboleth account can be used for this API user, but only a user who has registered via the local RADAR database with ID / PW. Thus please create a new RADAR API user that is used to retrieve the OAuth token with its credentials.

Example Library

An example library for common uses cases (Groovy and Python / curl) is available at: https://github.com/ER-FIZKarlsruhe/radar-api-demo

The examples include, e.g.:

  • Retrieve and renew OAuth tokens
  • View and create workspaces
  • Create a record with RADAR XML metadata
  • Upload individual files and archives
  • Check upload progress
  • Search content
  • Start and end a review
  • Validate metadata
  • Archive / publish a record

Target Systems

The following basic URLs are to be used for the API calls*: 

Development: https://test.radar-service.eu/radar/api/

Production: https://www.radar-service.eu/radar/api/

*not to be called up via the browser

Security

oAuth

Most of the endpoints requires an authenticated escidoc user to perform the action. In the RADAR all authentication is done via Oauth.

An API-Client has to send a valid Oauth Token in the request header to gain access to specific endpoints.

oAuth header:

Authorization: Bearer 0b79bab50daca910b000d4f1a2b675d604257e42

Dataset

Uploading files to a dataset

In the JSON file of the dataset there is an uploadURL and an ingestURL.

  • The /ingest endpoint can only be used for EMPTY datasets. Files in the formats zip/tar/tar.gz/tar.bz are extracted during ingest.
  • The /upload endpoint can be used to upload any single files. If files in the formats zip/tar/tar.gz/tar.bz are uploaded, these archives will then NOT be extracted.
  • If you want to upload via WebDAV, you must set the query parameter `webdav=true` when creating the dataset
