Abstract

Generally described, the present invention is directed to a network operating system that provides more effective ways of leveraging the connectivity of computer networks. In one embodiment, an XML virtual machine is implemented that accepts high-level application code written in an XML programming language as input. Functionality is provided to interpret or translate the application code written in an XML programming language into code that is suitable for execution across computer platforms. Moreover, the XML virtual machine supports the Model View Controller (MVC) design paradigm that facilitates true data abstraction from applications to a common data model. Multi-instance applications, with each instance potentially supporting multiple views, may be created and executed.

Claims

1. A platform independent XML virtual machine that accepts application code written in an XML programming language as input and implements a method that causes the application code to be executed on a computing device, the method comprising:

defining a set of runtime objects for executing an application including an instance object configured to couple operational meaning to the execution of the application'"'"'s process code;

providing low-level constructs (“

operation handlers”

) that execute operations defined in the application'"'"'s process code; and

implementing logic that allows stateless process objects to provide operation handlers with an instance object that accounts for changes in the application'"'"'s runtime state when executing the application'"'"'s process code.
