"whose rule is it anyway?" - A case study in the internationalization of user-configurable business rules

Abstract

This paper consists of a case study concerning the internationalization of an electronic invoice management web application and its central rules engine. It examines the challenges faced in introducing internationalization changes at the level of a custom scripting language processor and the problems inherent in maintaining compatibility with existing deployments. The paper outlines the specific solution and the ways in which the key concepts of locale context and lazy initialization may be applied to other similar internationalization problems. © 2009 Springer Berlin Heidelberg.
