XML Forms is a collection of Drupal modules for creating and updating XML metadata associated with repository objects though Drupal forms. The Islandora XML Form Builder (XML_Forms modules) makes it possible for users to create, copy, and edit ingest forms, and to affiliate them with Content Models in the repository.
The following modules are installed as part of the XML Forms package.
Objective Forms
This module allows for the creation of Object Based Drupal Forms. It provides a number of functions and class for processing/populating forms.
Some important notes.
- Each Form Element is assigned a unique hash Form Property to identify it, #hash.
- Each Form Element that is created is stored in a registry and it will persist though out the lifetime of the form even if it's removed from the form. Ancestry of Form Elements is stored so if a Form Element is cloned we will be able to determine the Form Element that it was cloned from.
- Form Properties can be objects. To define new Form Properties implement the hook objectify_properties.
- Forms will be auto-populated from $form_states[‘values’].
- There is a FormStorage class that can be used to store any persistent data.

Q. Can I convert an existing field to any form element type listed in the "Type" options under the "Common Form Controls" tab (or create new form elements using any form element type)?
A. No.
The following element types are not supported for full CRUD (create/read/update/delete) operations:
- checkbox
- checkboxes
- date
- file
- managed_file
- password_confirm
- radio
- radios
- tableselect
- vertical_tabs
- weight
- button
- image_button
- submit
Additionally, some form element types must be nested within another type. For example, tabpanel must be nested within tab.
