COAR Notify Test Inbox

This utility allows developers to post Linked Data Notifications and inspect the payload as received. Notifications are stored temporarily - you should have plenty of time to inspect the payload but no long-term persistence should be assumed.

Posting LDNs to the inbox

JSON-LD payloads should be posted to the LDN inbox here ( The following example uses Curl as the HTTP client and a local JSON-LD file containing the payload to be posted:

curl -s -o /dev/null -D - -X POST -H "Content-Type: application/ld+json" -d @<JSON-FILE-NAME>

Viewing the inbox and inspecting payloads and their metadata

Browser view

You can inspect the results of the posted payload by pointing your web browser at the same URL:

Here you will find links to inspect metadata and payloads in JSON-LD, N-Quads and Turtle formats

Machine-readable view

You can retrieve the inbox in JSON-LD format as follows:

curl -H "Accept: application/ld+json"

Getting Notifications directly

The URL for a given notification uses a generated UUID, in the form:<NOTIFICATION_UUID>

With a browser, this URL will give you a comprehensive view of the notification, its metadata and its payload in various formats.

To retrieve this notification's payload in machine-readable form, just issue a GET with the appropriate Accept header. Supported formats *(MIME Types) are:

For example:

curl -H "Accept: application/ld+json" <NOTIFICATION_URL>
