Evolution of Mobile Services

Graphical Applications

• Pop-down Menus

• Graphical Presentation

• Advanced Input

• Compound Forms

• Improved Layout

• Graphical Menus

10
Markup Language Evolution
HDML
11
XHTML Mobile Profile

• Strict superset of XHTML Basic
• XHTML Basic excludes many HTML features
  inappropriate for non-desktops
• Frames, fancy tables, event handlers, etc
• XHTML-MP provides extensions for mobile devices
• , ,
• WAP 2.0 browsers must also support WML 1.3 for
  backward compatibility
• XHTML and WML elements should not be mixed within
  the same document
• XHTML reduces development costs
• Developers leverage commonality in the language
  and development tools

12
CSS Mobile Profile

• Subset of CSS Level 2 (W3C) with WAP extension
  properties
• Tailored to the needs and constraints of mobile
  devices
• Allows style attributes to be defined separately
  from an XML document
• In the document element
• In a separate file element
• Enables smaller, portable, and personalized
  documents
• Documents can be adapted on the fly for new
  devices and end user preferences
• CSS is not a panacea!
• CSS does not allow one XHTML document to be
  created for all classes of Web clients
• CSS does not address all content adaptation
  issues
• Content structure, linkage, delivery, etc
