ProjectsThis is our list of candidate open source projects related to Orbeon Forms. Feel free to add your own: - Implementing the XProc W3C standard in Orbeon Forms
The goal of this project is to add support for the new XProc standard to Orbeon Forms, in addition to the existing XPL language. - An XForms engine dependency system for Orbeon Forms
Work on a state-of-the-art XPath dependency system for the XForms engine. - Port Orbeon Forms and Form Runner to the Google App Engine
The Google App Engine now supports Java. Orbeon Forms can eventually run on it, but it needs a new persistence implementation supporting the Google APIs. You will need to address the persistence implementation as well as make other changes to Orbeon Forms required by App Engine. - Support for a configurable data model in Form Builder
Design and implement a more flexible data model for Form Builder, possibly supporting XML Schema. - Add repeat / nested sections to Form Builder
Create a user interface to handle repetitions and nested sections to Form Builder. - Design a form data migration system based on static analysis of XML data
- Implement a state of the art caching mechanism
Orbeon Forms features a data cache, but it does not take into account the cost of recreating data once it expires. In this project, you can for example implement support for a cost-based algorithm based on the Greedy-Dual algorithms.
- Implement an automatic XForms generator based on an XML Schema description
In this project, you will implement an XML Schema to XForms converter. You can do this in several ways, including leveraging existing open source tools, or writing an entirely new solution.
