Background

Inevitable application migration– Same logic– Different language

Would storing application logic in a non- programming-language-specific format:– Helps application migration?– Allows for retargeting of application logic to

multiple types of components of different programming languages?

Research Objectives

To propose a framework that can facilitate the generation of different types of components in multiple languages

To implement a prototype that conforms to the proposed framework

To evaluate the prototype implementation

O2XML Framework

Focuses on OO-languages-based components Uses XML based markup language (O2XML) as an

intermediate representation of OO source codes Generates various types of components in different

OO languages

O2XML Framework Components

Source Code to O2XML Parser O2XML XSLT Transformer

– Outputs: Source codes

CodeDOM Generator– Outputs: Source codes, DLLs, EXEs

CodeDOM Technology

Part of .NET Framework Core:

– System.CodeDom namespace Builds in-memory object representation of source codes Classes: CodeCompileUnit, CodeTypeDeclaration,

CodeMemberMethod, CodeConditionStatement

– System.CodeDom.Compiler namespace Generates source codes, DLLs, and EXEs from the

object representation Classes: CodeDomProvider, CodeGenerator,

CodeCompiler
