WWW and Objects

• WWW is the "killer application" of the 1990s
  A user-friendly uniform interface to access any distributed resource

• WWW can be seen as an Object-Oriented Operating System:
  
  • A uniform naming with the Uniform Resource Locators
  • Persistent objects implemented via http daemons and their host file systems
  • An invocation meta-protocol through HTTP and a set of basic operations (GET, POST, ...)
  • Extensibility via the Common Gateway Interface protocol
• But
  • A same single "object interface" for all Web document resources
  • Other non standard Web resources are accessed by specific CGI programs
• Then
  • WWW needs a Uniform Object-Oriented Model to support new kinds of resources
