6: Hope for the Future!  

•    XML     (eXtensible Markup Language)
•  
  • separate information, display & interface  content   (good looks & brains)
  •  
  • tags for content, separate definition file for display, data structure
  •  
  • metalanguage: defines (info) sets of languages (VP for Socks)
  •  
  • tags  →  metadata (info about document's data = equations, figures);
  •  
  • data is structured & defined (dtd's):  useable  D documents (publish, Web, Palm)
  •  
  • user groups create tag sets (e.g. MathML)
•  
  • 1st: general syntax,  rich enough all structured info
•  
  •   non proprietary format → next generation of HTML (open info exchange)
  •  
  • e.g.:  ChemML,  MathML,  CommerceXML,  voiceXML,  BioSeqML, ebusML
  •  
  • W3C birth:  1996; XML 1.0: 1998 --------- 3 years affect
     
•   MathML
•  
  • XML application (W3C endorsed vocabulary)
•  
  • receive,  process, serve math, science over Web & documents (the future)
•  
  • needs browser support (plugin, enhancement)
•  
  • low level →  tedious to write → Converters (many)
•  
•   SVG    (Scalable Vector Graphics)
•  
  •  XML graphics format
  •  
  •  structural, visual content, data driven
  •  
  •  scriptable, interactive
