METHOD AND SYSTEM FOR VISUALLY CONSTRUCTING XML SCHEMAS USING AN OBJECT-ORIENTED MODEL

摘要

An object-oriented XML schema object model for use in a system for visualizingand constructing XML schemas is made up of a set of classes representative ofvariousXML schema components or categories thereof including XML schema files, globalXMLschema file content, global elements, non-global elements, element content,include files,import files, type definitions generally, complex type definitions, complextype definitioncontent, simple type definitions, built-in types, and attributes. The classesareimplemented in an object-oriented programming language and are instantiated asnecessary by the system in order to represent an XML schema being visuallyconstructed.By virtue of their interrelationships, the instantiated classes cumulativelyform an image orobject tree which efficiently and logically represents an XML schema beingvisualizedand/or constructed, and which may be easily navigated and modified during theexecutionof operations commonly encountered during XML schema visualization andconstruction.
