Foil 18 XML and Other Object Models

From Collaborative Portals for Distributed and Distance Learning NCSA Industrial Partners Meeting -- October 12-13 99. 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
