navigation in information space - selection of hyperlinks

We want to add links to XML like html's ...

Borrow it from the XLink definition using a Namespace declaration.

<Note>We can now have a <a xlink:href="http://...">link</a></Note>

entry of information - Xforms

Forms in HTML:

• don't check data types
• require lots of client side scripting
• difficult to develop
• error prone
• tied to one language - HTML

XForms provide an alternative in XML
strictly seperate the data model from the acquisition interface
XML Schema defines the data types to be collected
declarative control of the user interface elements

XForms implementations are being developed currently
