"Adobe has begun external beta tests of Adobe Designer 6.0, a graphical XML form design tool. [...] When combined with other Adobe document products and services, Designer connects to backend systems to automate business processes and collaboration between internal and external users.The software features a drag-and-drop interface with form elements based upon XML schema. To support migrations to XML, data can be imported from existing PDF and Microsoft Word templates. Completed forms are accessed through a Web browser or with Adobe’s Acrobat Reader.
According to Adobe, form data can be shared with systems through XML, OLEDB and Web services. Input fields dynamically resize as data is entered, and display fields that are relevant to the end user while leaving others out."
