Orbeon Forms allows to build and manage dynamic web forms, following the XForms XML specification. We use Orbeon Forms CE, released under open source LGPL license.

For Nasqueron, Orbeon Forms is deployed on the Docker PaaS and can be accessed at https://forms.nasqueron.org/

It allows forms administrators to create and read forms, and users to read fill forms. Those forms can be for a website or for a survey.

As of May 2023, the deployment is currently in testing mode on the "Dwellers" server. If the service has been moved to a different server, the references to "dwellers" in the procedures below should be replaced with the correct server name, for example "docker-002".

In the "Concepts" section, provide brief descriptions of Form Runner and Form Builder, explaining their respective functionalities.

Concepts

Orbeon Forms is divided in several applications:

  • Form Runner allows to fill a form and read form replies. For that, it reads a form in the XForms and connects to a database source.
  • Form Builder is an editor to visually design forms.

Once published, forms can be used different ways:

  • Through Form Runner. You direct the user to https://forms.nasqueron.org/orbeon/fr/<your app name>/<your form name>. It fills the form there, and afterwards is redirected to the configured URL.
  • As a storage back-end. You can also interact through Persistence API with the storage back-end.

Publish a form

The Form Builder is an editor to create a new form. You can also publish forms so they're accessible to the runner.

An access to the form builder is required. Browse:

Each form is identified by:

  • application name -> use an unique name for your application, with nasqueron- prefix, for example join.nasqueron.org uses nasqueron-join
  • form name -> use a short descriptive name for your form goal

Forms should also be published to the forms Git repository, so they're under version control, and can also be recreated if something goes wrong with the service database.

The repository is organized in subfolders, one per application. Each subfolder matches application name, without the nasqueron- prefix, for example join.nasqueron.org uses join/.

Authentication

Users are configured at Tomcat level. To add an user:

  • Provide Vault credential
    1. Create Vault credential under ops/secrets/nasqueron/orbeon/users/
    2. Add that credential in pillar/credentials/vault.sls
    3. Deploy new Vault policy sudo salt-call --local state.sls_id salt-node-dwellers roles/vault/policies
  • Declare the user in Tomcat configuration
    1. Edit pillar/paas/docker/dwellers/orbeon.sls
    2. Deploy it with salt dwellers state.sls_id /srv/orbeon/nasqueron_forms/conf/tomcat-users.xml roles/paas-docker/containers/orbeon, where nasqueron_forms is the name of our forms.nasqueron.orf instance
    3. Restart container: docker restart nasqueron_forms

Known issues

Authentication

Authentication is known to be rather buggy:

  • if you login at form runner level (e.g. /fr/admin), you can be unlogged at builder level
  • if you login from login form, you'll get a 403
  • if you login from builder, it can't tell you something is wrong

Configuration known issues:

  • If you got a 408 you accessed yourself /fr/login, but web.xml needs to be configured with a <login-config> block using the FORM auth method (that's the default Orbeon web.xml)
  • To enable login/logout menu, you need to add <property as="xs:boolean" name="oxf.fr.authentication.user-menu.enable" value="true" /> to properties-local.xml
