A major challenge in developing contemporary distributed software systems is dynamic accommodation of evolutionary change: modifications not envisaged at design time have to be handled at run time without disturbing those parts of the system unaffected by the change. The key feature of configuration management realizing such dynamic modifications and extensions is that semantic information about the constituent components has to be available in order to check the compliance wrt. adding a new or changed component. The aim of this thesis is to go beyond the currently available plug-in architectures such as CORBA, Java RMI or DCOM where the semantics of public interfaces is often only implicit or represented by very naive descriptions such as keyword lists or simple name/value pairs. The goal of these ideas is to achieve semantics-directed configuration of component based software systems in such a way that components organize themselves on the basis of a richer representation of their semantics concepts.
The main emphasis of this thesis lies on introducing different negotiation strategies and configuration protocols on top of semantics-directed component interaction. The final aim is automating most of this semantics-driven configuration process.
This thesis introduces the concepts for semantics negotiation and semantics-directed system configuration based on distributed graph transformation. Several non-trivial sample systems and case studies are presented in order to illustrate how the approach works. Finally, an overview of the tool environment implementing these ideas is given.
