Towards a service composition language for heterogeneous service environments

In this paper we provide an outline and characteristics of a language that allows the design of compositions within a heterogeneous service landscape. Heterogeneous refers to services from various industries and application domains like for example telecommunication, enterprise, web 2.0 and general IT. The language shall enable to use services from all these domains within a single service composition. We propose general requirements for this new language and we also offer an analysis of existing languages and their specific application domains. Finally, we discuss and propose extensions to an already existing standardized workflow language that enables heterogeneous compositions.
