Background

Inevitable application migration
–
–

Would storing application logic in a nonprogramming-language-specific format:
–
–
3
Same logic
Different language
Helps application migration?
Allows for retargeting of application logic to
multiple types of components of different
programming languages?

Research Objectives



4
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

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
