Collecting data on-line: XForms

• Current solution: use forms in HTML (and this is a disaster...)
  • no way to declare the types of data
  • requires lots of scripting support for any client-side check
  • bound to one host language (HTML)
• XForms will provide an alternative
  • strict separation of:
    • model (what is the data I want to collect?)
    • interface (how do I collect the data?)
  • data types for the information to be collected (using XML Schema)
  • declarative control of the user interface and behaviour
  • can be implemented on top of XHTML, SVG, Voice Browsers, etc
