for Uniform Object-Oriented Languages

Abstract. On one side the complexity of the design of distributed application systems is usually reduced significantly by using a distributed programming model that abstracts from the actual distribution and maybe even from the actual decomposition of the application. On the other side the developer needs to express the static and dynamic cooperation properties of the distrib-uted application and therefore needs to control its decomposition and distri-bution. An orthogonal distribution language (ODL) is presented. It allows the de-veloper to independently describe and adapt the decomposition and distribu-tion of an application written in a uniform object-oriented and distribution-transparent language independently; i.e. without affecting the semantics of the application.
