Architecture Choices

• Extend HTML:
  • + likely to meet appearance requirements: style sheets, frames
  • - unlikely to meet functional requirements
• Provide additional scripting capabilities (example: JavaScript)
  • + single specification of presentation and function
  • + most functional requirements can be met
  • - limitations of types of event notification
  • - some functional requirements not yet met
• Use Applets (examples: Java, Tcl/Tk)
  • + all presentational/functional requirements can be met
  • - specification "split" between HTML and applet
  • - complex interaction between browser and applet
