Foil 10 Logical versus Visual Design

From The Document Object Model - Universal Access - Other Objects - CORBA XML Jini JavaScript etc. Tango Seminar to DoD Modernization MSRC -- April 6 1999. by Geoffrey C. Fox
1 The logical design of a document (content) should be separate from its visual design (presentation)
2 Separation of logical and visual design
  • promotes sound typography
  • encourages better writing and is more flexible
3 HTML mixes the logical with the visual
4 Internal Representation of Microsoft Word/PowerPoint will/should be XML while "Save As HTML" should gives its visual rendering in HTML
  • XML structure of Word/PowerPoint can immediately be stored in a relational database
  • Dynamic HTML allows rendering of all features of these products whereas current export of Office products uses static images which are both unnecessarily large and incomplete representation
