Modelling Web-Oriented Architectures

Service-oriented architectures (SOAs) provide the basis of distributed application frameworks where software components are provided as modular and reusable services. Until today there is no generally accepted method for conceptual modelling of a SOA. Rather, there exist several procedural methods which are used in practice. On the other hand, recent developments in the context of what is commonly termed "Web 2.0" show how easy it can be to link or compose ("mesh") IT components dynamically, so that original SOA goals like flexibility, reusability, or reduction of complexity can indeed be achieved by relatively simple means. An interesting concept in this context is the Web-oriented architecture (WOA), which represents a specialization of SOAs obtained by using simple Web 2.0 technologies and standards (e.g., HTTP, SSL, XML). This paper introduces a methodology for designing WOAs, where the big picture follows existing SOA models. In particular, this WOA methodolog...
