Abstract.A new paradigm, known as Enterprise Mashups, has been gain momentum during the last years. By empowering actual business end-users to create and adapt individual enterprise applications, Enterprise Mashups implicate a shift concerning a collaborative software development and consumption process. Upcoming Mashup tools prove the growing relevance of this paradigm in the industry, both in the consumer and enterprise-oriented market. However, a market overview of the different tools is still missing. In this paper, we introduce a classification of Mashup tools and evaluate selected tools of the different clusters according to the perspectives general information, functionality and usability. Finally, we classify more than 30 tools in the designed classification model and present the observed market trends in context of Enterprise Mashups.

A new type of Web-based applications, known as Enterprise Mashups, has been gaining momentum in the last years. Novel design principles are currently about to emerge allowing to cover the long tail of user needs and to provide individual and heterogeneous enterprise applications in a shorter time. In this paper, we introduce the main components of this new paradigm, and discuss the design principles of the architecture (Enterprise Mashup Stack), upcoming intermediaries and mass collaboration, lightweight composition as well as perpetual beta development model.

Introducing process orientation to overcome the functionaloriented organizational structure was the main concern within enterprises during the last decade to improve process quality. The next wave of process-oriented enterprises deals with integrating private tasks and processes into cross-organizational business processes characterized by high automation effort and supported by a wide penetration of e-Business technologies. In this work, we propose a concept for transforming internal private processes to publicly visible processes in a semi-automatic way. This transformation will be done by hiding the modelling complexity from the users. Evaluated on the basis of Event-Driven Process Chains (EPC) for private process view and the Business Process Modelling Notation (BPMN) for public process view, this article identifies the challenges both on semantic and syntactic level regarding the integrated mapping between different modelling layers as well as modelling languages.

The huge demand for situational and ad-hoc applications desired by the mass of business end users cannot be fully covered by traditional Service-Oriented Architectures (SOAs). By putting a face on SOA, Enterprise Mashups empower these end users to combine and reuse Web-based resources within minutes to create value added applications. In this paper, we present the SAP Research RoofTop Marketplace prototype that transfers established marketplace concepts to the Enterprise Mashup paradigm in order to leverage the power of peer production. The underlying concepts and the resulting architecture of the platform are presented. By means of a business scenario, the features of the grassroost Enterprise Mashup platform are demonstrated.
