POSTing null content

Greetings,

I am attempting to communicate with a REST interface for a fedora repository and am experiencing difficulty in one area. According to the documentation [https://wiki.duraspace.org/display/FEDORA35/REST+API#RESTAPI-ingest], you can POST with no request content which will then create a blank object in the repository.

The following curl commons works just fine:

curl -u fedoraAdmin:fedoraAdmin -X POST http://localhost:8080/fedora/objects/new?namespace=test

My submission in Orbeon looks like this:

<xforms:submission

method="post"

action="http://localhost:8080/fedora/objects/new?namespace=test"

xxforms:username="fedoraAdmin"

xxforms:password="fedoraAdmin"

This submission generates HTTP error 415 from the fedora repository stating “The server refused this request because the request entity is in a format not supported by the requested resource for the requested method”

So I guess I have a couple of questions.

1) What am I POSTing to the REST interface if I am not specifying a specific instance?

2) Is there a way to POST to an interface without specifying any content?

Thanks,

David Lacy

Hi Dave,

Not specifying a ref="…" is the same as having a ref="instance()", that is submitting your first instance. If you don't want anything to be submitted, I would add serialization="none", as in:

<xforms:submission id="s" method="post" serialization="none" action="/" replace="instance"/>
