  1. XHTML/XForms/XML Eventsvs. UIML Marc Abrams Abrams@vt.edu April 2002

  2. Philosophy • HTML is on a path to separate pieces of a UI: • Step 1: everything mixed together in HTML 3.2 • Step 2: separate style (CSS, XSL-FO) • Step 3: separate forms (XML Forms) • Step 4: separate events (XML Events) • UIML started by asking, “what is ultimate separation?” • Answer: 6 elements (part structure, style, content, behavior, APIs, mapping abstract names to target toolkit)

  3. Where UIML Fits W3C World* Application database Content (XML, audio,…) Device Adaptation UIML XHTML VoiceXML XForms … * Diagram from Dave Raggett’s W3C Bristol talk, Fall 2000

  4. UIML and XForms/XHTML • XForms is very helpful for UIML • XForms makes Web-based forms more powerful

  5. XForms Reduces “distance” UIML Renderer Java VoiceXML XForms/XHTML More Primitive WML HTML 3.2, 4.0

  6. XForms Versus UIML

  7. XML Events vs. UIML Behavior (1) • XML Events annotate XML tree:attach <listener> to XML tree elements • XML Events view:What events can happen for this node? • UIML behavior takes HCI – UIMS view: what is theoretically most powerful way to describe UI behavior? Answer is an event-based condition/action pairs.

  8. XML Events vs. UIML Behavior (2) • XML Events: if event X happens for XML tree node Y then do Z • UIML Behavior: if condition A holds then do B whereconditioncould be arbitrary Boolean expression involving X
