On W3C’s XForms mailing list, Jan-Felix Schwarz has announced the Oryx XForms Editor, a web-based tool for creating XForms. You can visually edit forms, export and import them in XForms format. The editor runs in your web browser (Firefox), zero software installation required. The editor is still in an early stage and is currently available for testing and feedback.
Oryx is an open platform for web-based modeling developed by the Business Process Technology research group at the Hasso Plattner Institute of IT Systems Engineering at the University of Potsdam. Besides XForms, Oryx supports various modeling languages, like BPMN, EPC and Petri nets.

Everyone is invited to contribute new features and knowledge to Oryx. The project is hosted as a Google Code project under MIT license.
