“…Here computation and coordination are clearly separated, communication becomes anonymous and component interconnection is externally controlled. This model is (partially) implemented in JavaSpaces on top of Jini [33] and fundamental to a number of approaches to componentware which identify communication by generic channels as the basic interaction mechanism -see, e.g., Reo [3], Piccola [43,32], as well as [16,13] or [10].…”

Abstract. This paper provides an overview of an approach to coalgebraic modelling and refinement of state-based software components, summing up some basic results and introducing a discussion on the interplay between behavioural and classical data refinement. The approach builds on coalgebra theory as a suitable tool to capture observational semantics and to base an abstract characterisation of possible behaviour models for components (from partiality to different degrees of non-determinism).

Summary.In recent years, so-called scripting languages have become increasingly popular as they provide means to build quickly flexible applications from a set of prefabricated components. These languages typically support a single, specific architectural style of composing components (e.g. the pipes and filters architectural style), and they are designed to address a specific application domain. Although scripting languages and coordination languages have evolved from different roots and have been developed to solve different problems, we argue that both address similar separations of concerns. Scripting languages achieve a separation of components from the scripts that configure and compose them, whilst coordination languages separate computational entities from the coordination code that manages dependencies between them. In this chapter we will define coordination in the context of a conceptual framework for component-based software development. Furthermore, we will discuss main properties and abstractions of scripting languages and will compare selected scripting languages with respect to the identified core concepts. Finally, using a small set of sample applications, we will illustrate the power and the limitations of these concepts in order to define agent coordination.

“…Solutions tend to be limited to the combination of just content rather than applications, overlooking end users and their participation. A high dependency on the underlying computing infrastructure is another limiting factor (Schneider, 1999). Also, changesinthe original wrapped applications, the backend services or the portal infrastructure may cause a user interface (UI) failure and disable user-service interaction because there is no formal user-centred framework.…”

a b s t r a c tEnabling real end-user development is the next logical stage in the evolution of Internet-wide service-based applications. Successful composite applications rely on heavyweight service orchestra-tion technologies that raise the bar far above end-user skills. This weakness can be attributed to the fact that the composition model does not satisfy end-user needs rather than to the actual infrastructure technologies. In our opinion, the best way to overcome this weakness is to offer end-to-end composition from the user interface to service invocation, plus an understandable abstraction of building blocks and a visual composition technique empowering end users to develop their own applications. In this paper, we present a visual framework for end users, called FAST, which fulfils this objective. FAST implements a novel composition model designed to empower non-programmer end users to create and share their own self-service composite applications in a fully visual fashion. We projected the development envi-ronment implementing this model as part of the European FP7 FAST Project, which was used to validate the rationale behind our approach.
