Create binary without type

curl -v -XPOST -ufedoraAdmin:fedoraAdmin -H"Content-Disposition: attachment; filename=\"postCreate.txt\"" -H"Slug: binary_change_test1" --data-binary "TestString." http://localhost:8080/rest/


curl -v -ufedoraAdmin:fedoraAdmin http://localhost:8080/rest/binary_change_test1

Try to change type to a BasicContainer while also providing binary content

curl -v -XPUT -ufedoraAdmin:fedoraAdmin -H"Content-Disposition: attachment; filename=\"putCreate.txt\"" -H'Link: <http://www.w3.org/ns/ldp#BasicContainer>;rel="type"' --data-binary "TestString2." http://localhost:8080/rest/binary_change_test1

< HTTP/1.1 204 No Content

Check what the result was, which appears to be no change to the type

curl -v -ufedoraAdmin:fedoraAdmin http://localhost:8080/rest/binary_change_test1

< HTTP/1.1 200 OK

# TestString2.

Try to change type to RDFSource while also providing binary content

curl -v -XPUT -ufedoraAdmin:fedoraAdmin -H"Content-Disposition: attachment; filename=\"putCreate2.txt\"" -H'Link: <http://www.w3.org/ns/ldp#RDFSource>;rel="type"' --data-binary "TestString3." http://localhost:8080/rest/binary_change_test1

< HTTP/1.1 400 Bad Request
Invalid interaction model: http://www.w3.org/ns/ldp#RDFSource

Change type to RDFSource without binary

curl -v -XPUT -ufedoraAdmin:fedoraAdmin -H'Link: <http://www.w3.org/ns/ldp#RDFSource>;rel="type"' http://localhost:8080/rest/binary_change_test1

< HTTP/1.1 400 Bad Request
# Invalid interaction model: http://www.w3.org/ns/ldp#RDFSource

Try to change type to BasicContainer without any binary related info

curl -v -XPUT -ufedoraAdmin:fedoraAdmin -H'Link: <http://www.w3.org/ns/ldp#BasicContainer>;rel="type"' http://localhost:8080/rest/binary_change_test1

< HTTP/1.1 204 No Content


curl -v -ufedoraAdmin:fedoraAdmin http://localhost:8080/rest/binary_change_test1

< HTTP/1.1 200 OK
< Link: <http://www.w3.org/ns/ldp#Resource>;rel="type"

< Link: <http://localhost:8080/rest/binary_change_test1/fcr:metadata>; rel="describedby"
< Content-Type: application/octet-stream
< Content-Length: 0

Also worth noting is that the Content-Type is no longer

Try to change to a DirectContainer

curl -v -XPUT -ufedoraAdmin:fedoraAdmin -H'Link: <http://www.w3.org/ns/ldp#DirectContainer>;rel="type"' http://localhost:8080/rest/binary_change_test1

< HTTP/1.1 409 Conflict
# Changing the interaction model ldp:BasicContainer to ldp:DirectContainer is not allowed!

What?? Its supposed to be a NonRdfSource, not a basic container

I also got a 204 response and the same behavior for NonRDFSource to IndirectContainer and DirectContainer. It did not matter if I explicitly provided the NonRDFSource type when creating the binary.

And just to be safe... lets see what happens if creating a child in our NonRDFSource that thinks its a BasicContainer

curl -v -XPUT -ufedoraAdmin:fedoraAdmin http://localhost:8080/rest/binary_change_test1/child

< HTTP/1.1 409 Conflict
Unable to add child /child to resource /binary_change_test1

phew...
