Standard support

Introduction

Orbeon Forms supports most standard XForms features, including:
  • the specified processing processing model
  • events: xforms-submit, xforms-submit-serialize, xforms-submit-done, and xforms-submit-error
  • all HTTP and HTTPS methods
  • serializations: application/x-www-form-urlencoded, application/xml, application/json (SINCE Orbeon Forms 2016.1), multipart/form-data, as well as extensions.
  • replacements: all, instance, and text
  • SOAP support
One exception is the lack of support for multipart/related.
For more information, please visit the XForms 1.1 specification.

JSON support

Controlling non-relevant nodes

[SINCE Orbeon Forms 2017.1]
The XForms 2.0 nonrelevant attribute takes values
  • keep: all values are serialized,
  • remove: non-relevant values are not serialised
  • empty: non-relevant nodes are serialized as empty values
The default is remove.
1
<xf:submission id="my-submission"
2
method="post"
3
nonrelevant="empty"
4
resource="http://example.org/rest/draft/"
5
replace="none"/>

Disabling validation and relevance handling

Orbeon Forms supports the XForms 1.1 validate and relevant attributes on <xf:submission>.
NOTE: The relevant attribute is deprecated in favor of the XForms 2.0 nonrelevant attribute.
These boolean attributes disable processing of validation and relevance pruning respectively for a given submission:
1
<xf:submission id="my-submission"
2
method="post"
3
validate="false"
4
relevant="false"
5
resource="http://example.org/rest/draft/"
6
replace="none"/>
Copied!
XForms 2.0 introduces nonrelevant (while keeping relevant for backward compatibility) for clarity:
1
<xf:submission id="my-submission"
2
method="post"
3
validate="false"
4
nonrelevant="keep"
5
resource="http://example.org/rest/draft/"
6
replace="none"/>
Copied!

Controlling serialization

Orbeon Forms supports the XForms 1.1 serialization on <xf:submission>. This is particularly useful to specify the value none with a get method:
1
<xf:submission id="my-submission"
2
method="get"
3
serialization="none"
4
resource="http://example.org/document.xml"
5
replace="instance"
6
instance="my-instance"/>
Copied!
