Form metadata API
Service endpoint
HTTP GET to the following path:
1
/fr/service/persistence/form
Copied!
Purpose
This is the API used, in particular, by the Form Runner Home page, accessible to users on /fr/. The Form Runner home page lists all the published forms the user has access to, and for each one it provides a link to create a new instance of that form, and to the summary page for that form. Either one of those links might be missing, depending on the user's permissions.
API
Request
Basics
You get the list of all the published forms with a GET on:
1
/fr/service/persistence/form
Copied!
This, in turn, calls the corresponding API for each persistence API implementation defined in the properties as active, since different forms can be published on different persistence implementations. For example, this might call MySQL implementation doing a GET on:
1
/fr/service/mysql/form
Copied!
Then it might call the eXist implementation with another GET on:
1
/fr/service/exist/form
Copied!
Finally it aggregates the results returned by each implementation.
Restricting by app/form name
[SINCE Orbeon Forms 4.3]
Optionally, an app name or both an app name and form name can be specified on the URL. In that case, the API only returns information about published forms in that specific app, or that specific app and form is returned.
When an app specified, the URL looks like:  
/fr/service/persistence/form/[APP_NAME]
When both an app and form name are specified, the URL looks like:  
/fr/service/persistence/form/[APP_NAME]/[FORM_NAME]
Returning all form definition versions
[SINCE Orbeon Forms 2016.2]
Optionally, you can pass the URL parameter all-versions:
when set to true
All form definition versions are returned.
when omitted or set to false
Only the form definition with the highest published version number is returned.
Returning all form definitions
[SINCE Orbeon Forms 2019.1, 2018.2.1, 2018.1.4, 2017.2.3]
Optionally, you can pass the URL parameter all-forms:
when set to true
all forms are returned without checking for permissions or other criteria
when omitted or set to false (which was the behavior before all-forms was supported)
Only forms to which the user has "access" are returned.
If the user has access as per form-builder-permissions.xml, then all form definitions are returned.
Otherwise:
library form definitions are excluded 
forms which have permissions defined and for which the user has no permissions at all are excluded
unavailable form definitions are excluded
Filtering by date
[SINCE Orbeon Forms 2021.1]
Optionally, you can pass the URL parameter modified-since:
this must be an ISO date/time
when passed, only form definitions which have been modified since the given date are returned
For example:
1
/fr/service/persistence/form?modified-since=2021-09-09T04:56:42.257Z
Copied!
Response
Response format
Each <form> element contains:
<application-name>
<form-name>
All the elements inside the form metadata instance of the corresponding form definition
This can be retrieved with the following XPath expression:  
/xh:html/xh:head/xf:model/xf:instance[@id = 'fr-form-metadata']/metadata/*
[SINCE Orbeon Forms 2016.1]
The <description> and <migration> elements are excluded.
<last-modified-time>
[SINCE Orbeon Forms 4.4]
[UNTIL Orbeon Forms 4.10.x]
last modification date/time for the app/form combination
[SINCE Orbeon Forms 2016.1]
last modification date/time for the app/form/version combination
<form-version>
[SINCE Orbeon Forms 2016.1]
contains the version number of the given <form>
NOTE: This is only returned when using a relational database, as the implementation of the persistence API for eXist doesn't support versioning yet.
<available>
set to false when the form definition is marked as not available
