When using GET and PUT to deal with resources, the body of HTTP requests contains the resource to handle.

  • GET
    • The request body is empty and response body contains resource.
    • [SINCE Orbeon Forms 4.5] The Orbeon-Operations response header lists the operations that the user can perform on the data (see Supporting permissions in your persistence API implementation).
    • [SINCE Orbeon Forms 4.5] If the implementation of the persistence API supports form versioning, and the request is for a form definition, the Orbeon-Form-Definition-Version request header tells which version of the form definition is requested.
  • PUT
    • The request body contains the resource to store.
    • The Content-Type must contain the content-type of the resource to store. For XML in particular, pass application/xml.
    • The request response is empty.
    • If your implementation of the persistence API supports form versioning, then when storing a new document, you need to tell the persistence what version of the form definition was used to create this data, so the same version can then be used to subsequently edit the data. This is done by specifying the version in the Orbeon-Form-Definition-Version header.
    • Both request and response bodies are empty.

When the resource is an XML file (e.g. form.xhtml, data.xml), the persistence layer must return an appropriate XML content-type: application/xml, or application/xhtml+xml.

Example using curl

The following uses the curl command-line utility to PUT a form definition so that it's available to Form Builder (indented for clarity):

  -d @mydata.xml
  -H "Content-Type: application/xml"
  -H "Orbeon-Form-Definition-Version: 1"
  -X PUT

The following retrieves the data (the GET method is used implicitly):

  -H "Orbeon-Form-Definition-Version: 1" 

URL parameters

Supported by the persistence implementation

[SINCE Orbeon Forms 2017.1]

  • nonrelevant
    • when using GET for data only
    • values
      • remove: remove all XML data elements with attribute fr:relevant="false"
      • missing: do not remove XML data elements

NOTE: This property only operates properly on data stored with Orbeon Forms 2017.1 and newer, as only Orbeon Forms 2017.1 and newer stores data with the fr:relevant="false" annotation.

Passed by Form Runner

[SINCE Orbeon Forms 4.2]

The following URL parameters are set by Form Runner:

  • valid
    • passed when data is stored using PUT only
    • values
      • true: data sent satisfies validation rules
      • false: data sent does not satisfy validation rules

This allows a persistence implementation to store this information if desired.


Publishing from Form Builder

When you create, edit, or read form definition with Form Builder, form definitions are stored as Form Builder data. That is, they are stored under:


On the other hand, when Form Builder publishes a form definition, it stores it where Form Runner will find it, that is under:


For example, this is what happens when saving and publishing a form definition acme/demo with a single attachment:


  • PUT /crud/orbeon/builder/data/7b55c9d6f9b058376293e61d9f0d4442e379f717/a29fd47011b2957ef44a62d92995adfdbae03fa9.bin
  • PUT /crud/orbeon/builder/data/7b55c9d6f9b058376293e61d9f0d4442e379f717/data.xml


  • PUT /crud/acme/demo/form/a29fd47011b2957ef44a62d92995adfdbae03fa9.bin
  • PUT /crud/acme/demo/form/form.xhtml?document=7b55c9d6f9b058376293e61d9f0d4442e379f717

[SINCE Orbeon Forms 4.6]

When Form Builder publishes a form definition, if versioning is supported by the target persistence layer, it passes a Orbeon-Form-Definition-Version header with values:

  • next: to indicate that the form definition must be published under the next available version
  • or a specific version number: to indicate that the form definition must replace the given version

Deleting all data for an existing form

To remove all instances of form data, issue a DELETE to:
