A meta-model driven methodology for state transfer in component-oriented systems
Abstract
State transfer between versions is one of the most difficult challenges related to online upgrading.This position paper describes a methodology that attempts to solve this problem using meta-models constructed from the source of a component.This meta-model is subsequently modified to prepare the component for run-time replacement.The methodology uses heuristics and algorithms to anticipate which member variables in different component versions are meant to correspond.Additional semantic information is provided by the user.The proposed technique offers full separation of concerns,and has prospects to include intelligent state transfer support for live update systems.
