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.
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
.
For callers, when PUT
ting data under the path /orbeon/builder/data/
, which means storing unpublished form definitions and form definition attachments, always set Orbeon-Form-Definition-Version
to the value 1
, or omit the versioning header (which defaults to 1 for new data, and to the latest version of the resource for existing data). This is because Form Builder stores its unpublished form definitions like a regular published form would, but in effect there is only one "version" of Form Builder.
For a particular application name and form name, the document id must be unique. The document id cannot be reused across form definition versions. This allows the document id to be used to infer the form definition version number when retrieving data for a given application name and form name.
When using PUT
to update a resource (whether form data or attachment), the built-in relational persistence layer checks that the version number provided matches the existing version number in the database. Custom persistence layers should do the same.
For example, if you PUT
an attachment with path (indented for legibility):
/fr/service/persistence/crud/acme/order/data/fc4c32532e8d35a2d0b84e2cf076bb070e9c1e8e/8bf211aef805f1354129ee47cc0964d256ba7cae.bin
and pass the header:
Orbeon-Form-Definition-Version: 3
and there is already, in the database, such an attachment that was created with version 3, the request is successful and the resource is updated.
On the other hand if, for the same resource, you pass the header:
Orbeon-Form-Definition-Version: 4
the persistence layer returns a 400
"Bad Request" HTTP status code.
The following examples use the curl command-line utility. They are indented on multiple lines for clarity but in practice each command must be written on a single line.
The service must be open for these examples to work. See Authorization of pages and services.
The general format of the a path to access form data is:
/fr/service/persistence/crud/$app/$form/(data|draft)/$doc/data.xml
So with the following assumptions:
app name ($app
): acme
form name ($form
): order
document id ($doc
): fc4c32532e8d35a2d0b84e2cf076bb070e9c1e8e
then you can PUT
form data as follows:
curl-v-k-d @mydata.xml-H "Content-Type: application/xml"-H "Orbeon-Form-Definition-Version: 1"-X PUThttp://localhost:8080/orbeon/fr/service/persistence/crud/acme/order/data/fc4c32532e8d35a2d0b84e2cf076bb070e9c1e8e/data.xml
The following retrieves the data (the GET
method is used implicitly by curl):
curl-v-k-H "Orbeon-Form-Definition-Version: 1"http://localhost:8080/orbeon/fr/service/persistence/crud/acme/order/data/fc4c32532e8d35a2d0b84e2cf076bb070e9c1e8e/data.xml
The same API is used by Form Builder to store in-progress (unpublished) form definitions under the orbeon/builder
app/form names. So with the following assumptions:
app name ($app
): orbeon
form name ($form
): builder
document id ($doc
): 7b55c9d6f9b058376293e61d9f0d4442e379f717
then you can PUT
a form definition so that it's available to Form Builder:
curl-v-k-d @mydata.xml-H "Content-Type: application/xml"-H "Orbeon-Form-Definition-Version: 1"-X PUThttp://localhost:8080/orbeon/fr/service/persistence/crud/orbeon/builder/data/7b55c9d6f9b058376293e61d9f0d4442e379f717/data.xml
The following retrieves the form definition (the GET
method is used implicitly):
curl-v-k-H "Orbeon-Form-Definition-Version: 1"http://localhost:8080/orbeon/fr/service/persistence/crud/orbeon/builder/data/7b55c9d6f9b058376293e61d9f0d4442e379f717/data.xml

The following URL parameters are set by Form Runner:
valid

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.
Example:

When you create, edit, or read form definition with Form Builder, those are considered unpublished form definitions and are stored as Form Builder data. Those are . They are stored under the path:
/crud/orbeon/builder/data/$doc
On the other hand, when Form Builder publishes a form definition, Form Builder first makes modifications to the form definition (such as adding section templates) and stores it where Form Runner will find it, under the path:
/crud/$app/$form/form
For example, this is what happens when saving and publishing a form definition acme/order
with a single attachment (for example for a PDF template or static image):
Save:
PUT /crud/orbeon/builder/data/7b55c9d6f9b058376293e61d9f0d4442e379f717/a29fd47011b2957ef44a62d92995adfdbae03fa9.bin
PUT /crud/orbeon/builder/data/7b55c9d6f9b058376293e61d9f0d4442e379f717/data.xml
Publish:
PUT /crud/acme/order/form/a29fd47011b2957ef44a62d92995adfdbae03fa9.bin
PUT /crud/acme/order/form/form.xhtml?document=7b55c9d6f9b058376293e61d9f0d4442e379f717
[SINCE Orbeon Forms 4.6]
When Form Builder publishes a form definition, if versioning is supported by the target persistence layer, it passes an Orbeon-Form-Definition-Version
header with values:
missing: indicates the latest published version, or 1
if there is no published version
next
: to indicate that the form definition must be published under the next available version
or a specific version number: to indicate that the form definition must replace the given version
NOTE: The version number must be a positive integer.
[SINCE Orbeon Forms 2017.2.]
Orbeon Forms implements, exposes, and internally uses the Publish form definition API to publish form definitions. Orbeon recommends using that API to publish form definitions.
Form data supports attachments. These are usually binary data attached by the user via an Attachment or Image attachment control. Attachments are stored separately from the XML data.
In order to save an attachment, you have to use a separate PUT
request for each attachment. Conversely, to read an attachment that has been saved, use a GET
to the attachment path. The format of the attachment path is as follows, on a single line (here split in multiple lines for readability):
/fr/service/persistence/crud/$app/$form/(data|draft)/$doc/$attachment.bin
where $attachment
is a random id for the attachment. The .bin
extension is expected.
The XML data must point to the attachment using that same path. For example:
<form><my-section><my-imagefilename="MyImage.jpg"mediatype="image/jpeg"size="22143">/fr/service/persistence/crud/orbeon/bookshelf/data/16ab5903c7f0deb74fdc51dbdf705375/26abcf492f64db9808f2b13847e0cf8b.bin</my-image></my-section></form>
Note that in the case of attachments, the XML data contains attributes indicating:
the file name
the mediatype
the file size
[SINCE Orbeon Forms 2019.1] Implementations of the persistence API don't need to do anything special to handle encrypted attachments, and they can just save the data they received and serve the data they saved. Conversely, consumers of the persistence API will always receive decrypted data when issuing a GET
request and aren't expected to do the encryption themselves when issuing a PUT
request. This ensures that the persistence API is as simple as possible to both implementers and users of the persistence API.
For this to work, a component we call the persistence proxy sits between consumers and implementations of the API. It is the persistence proxy that takes care of encrypting and decrypting attachments as necessary. However, for the persistence proxy to be able to do this, as a consumer of the API:
When storing an attachment (PUT
), you must "tell" the persistence proxy what field this attachment corresponds to, so the persistence proxy can figure out whether it needs to be encrypted based on the form definition. This is done by adding an Orbeon-Path-To-Holder
header to your PUT
request. The value of the header is the path to the element in the XML data that corresponds to the attachment currently being stored. The path should skip the root element name (/form
), but include "iteration" elements for repeated grids and repeated sections. For instance:
If you have a section named personal-information
, with an attachment field photo
, then the value of the header should be personal-information/photo
.
If you have a section named children
, with a repeated grid named child
, with an attachment field photo
, then the value of the header should be children/child/child-iteration/photo
.
When reading an attachment (GET
), you must "tell" the persistence proxy whether the attachment was encrypted. You can know this by checking whether the element in the XML data that corresponds to the attachment has an attribute fr:attachment-encrypted = 'true'
. If so, you need to add the header Orbeon-Decrypt: true
to your GET
request. (The fr:attachment-encrypted = 'true'
attribute in the XML data is automatically set or removed, as appropriate, by the persistence proxy when the data is saved.)
To remove all instances of form data, issue a DELETE
