Modelling architectural design rules in UML

Current techniques for modelling software architecture do not support the modelling of architectural design rules, which are recognized as important design artefacts by current research in software architecture. This is a problem in the context of Model-Driven Development in which it is assumed that major design artefacts are represented as formal or semi-formal models. This paper addresses this problem by proposing how architectural design rules could be expressed in UML in a meta-model for the system model
