	abstract = {The REST architectural style has attracted a lot of interest from industry due to the nonfunctional properties it contributes to Web-based solutions. SOAP/WSDL-based services, on the other hand, provide tools and methodologies that allow the design and development of software supporting complex service arrangements, enabling complex business processes which make use of well-known control-flow patterns. It is not clear if and how such patterns should be modeled, considering RESTful Web services that comply with the statelessness, uniform interface and hypermedia constraints. In this article, we analyze a set of fundamental control-flow patterns in the context of stateless compositions of RESTful services. We propose a means of enabling their implementation using the HTTP protocol and discuss the impact of our design choices according to key REST architectural principles. We hope to shed new light on the design of basic building blocks for RESTful business processes.},

	abstract = {End-User Development (EUD) can be exploited on the Web, where users have the opportunity to create niche {\textquotedblleft}Web Mashup{\textquotedblright} applications as a means to address their long tail of situational needs in different domains of application. In this paper, we describe the design and evaluation of NaturalMash, an innovative EUD system for mashups. NaturalMash provides a high level of expressive power while it is still usable by non-professional users. This clearly distinguishes NaturalMash from existing mashup EUD tools that are either too limited or highly specialized for inexperienced users. The NaturalMash user interface efficiently combines different techniques such as live programming, natural language programming, What You See Is What You Get (WYSIWYG), and Programming by Demonstration (PbD). The design of NaturalMash adopts a formative evaluation approach, and has completed two design and evaluation iterations. The paper reports the results of the last formative evaluation and discusses the implications of the findings. The results are promising and suggest that the proposed system has a short and gentle learning curve and enables even non-professional users to rapidly build useful mashups.},

	abstract = {Service-oriented architectures (SOAs) provide a successful model for structuring complex distributed software systems, as they reduce the cost of ownership and ease the creation of new applications by composing existing services. However, currently, the development of service-oriented applications requires many manual tasks and prevailing infrastructure is often based on centralized components that are central points of failure and easily become bottlenecks. In this paper, we promote self-organizing SOA as a new approach to overcome these limitations. Self-organizing SOA integrates research results in the areas of autonomic and service oriented computing. We consider self-organizing features for the whole life-cycle of a service-oriented application, from the creation to the execution, optimization, and monitoring.},
