Foil 9 XML and Other Object Models

From Portals for Web Based Education and Training Rice University Tango Tutorial -- October 18 1999. by Geoffrey C. Fox
So XML Web pages are natural XML specified objects but you can use XML as export of an Oracle database
COM and CORBA define their interfaces in a specialized IDL (Interface Definition Language)
Java defines its object interfaces in terms of Java the language
But it does not matter if object is in text file, C (accessed via CORBA or COM), Oracle, Java or JavaScript; one can define interface in XML and map to particular realization
So XML is Universal Object Specification
  • it may or may not be preferred object implementation
