Removing resources, media and files - DELETE Requests

Deleting is as easy as getting resources and more difficult than creating resources.

If you can perform a GET request then you have the information required to perform a DELETE request.

Check out the examples below.

Authorization

If you have restricted access to view your content, you will need to use one of the configured authorization methods to access your content, media and/or files.

These are defined under Authorization on the overview.

Content (Nodes)

You will need your node id, you can find more information in the GET documentation.

A delete is simply the same request as a GET but sending a DELETE http verb.

Our example node has a node id of 2

> curl -i -u admin:islandora -X GET 'http://localhost:8000/node/2?_format=json'

Then we switch GET to DELETE

> curl -i -u admin:islandora -X DELETE 'http://localhost:8000/node/2?_format=json'

Media

You will need a media id as used in GET documentation.

A delete is simply the same request as a GET but sending a DELETE http verb.

With a media id of 1 for our example, I'll perform a GET

> curl -i -u admin:islandora -X GET 'http://localhost:8000/media/1?_format=json'

Then we replace GET with DELETE.

> curl -i -u admin:islandora -X DELETE 'http://localhost:8000/media/1?_format=json'

Subsequent requests to the media return 404 Not Found statuses.

> curl -i -u admin:islandora -X GET 'http://localhost:8000/media/1?_format=json'

Files

You'll need the file id, there is more information at the top of the GET requests for files documentation.

A delete is simply the same request as a GET but sending a DELETE http verb.

With a file id of 2 for our example, I can perform a test GET

> curl -i -u admin:islandora 'http://localhost:8000/entity/file/2?_format=json'

If this is the correct file, I can delete it.
