    A new kind of Web-based application, known as Enterprise Mashups, has gained momentum in the last years: Business users with no or limited programming skills are empowered to leverage in a collaborative manner user friendly building blocks and to combine and reuse existing Web-based resources within minutes to new value added applications in order to solve an individual and ad-hoc business problem. Current discussions of the Mashup paradigm in the scientific community are limited on technical aspects. The collaboration and the peer production management aspects of the Mashup development have received less attention yet. In this paper, we propose a reference model for Enterprise Mashups which provides a foundation to develop and to analyse grassroots Enterprise Mashup environments from a managerial and collaborative perspective. By following the design science research approach, we investigate existing reference models and leverage the St. Gallen Media Reference Model (MRM). The development of Enterprise Mashups is structured by market transaction phases similar to electronic markets. The user roles, the necessary processes and the resulting services are modelled according to the views of the MRM. By means of the SAP Research RoofTop Marketplace prototype we demonstrate the application of the designed reference model for grassroots Enterprise Mashups environments.

    Internet of Services - Lightweight Composition and Enterprise Mashups @ SAP Research St. Gallen

    Nowadays, Service-oriented Architectures (SOA) focus mainly on firm intern integration of applications and are not widely adopted to support the emerging globally networked information service economy. On hurdle observed on the way to a truly global approach to SOA is the fact that performance of information services is low compared to more mature industries. Current technologies and architectures do not provide efficient and effective support. However, recently numerous novel use cases demonstrate the great potential of combining the technologies and principles of Web 2.0 and SOA. One major example of the convergence of the two philosophies is the emergence of an Internet of Services (IoS). Up to now, normal Internet users with little IT sophistication haven't been able to easily retrieve and use certain services. This is because these services mostly reside within company boundaries and are only accessed for professional use in a corporate context. However, the provision of easily accessible services for end users might drive a novel generation of Internet use and allow for the ad-hoc setup and configuration of IT supported business models. Without an intuitive "face" toward human users, Web-based services will remain fairly unusable by the common Web surfer, because currently these interfaces (such as those described in WSDL) are designed to be processed by machines. New concepts emerging to solve the described problems are lightweight composition and enterprise mashups. Enterprise mashups in an Enterprise context aim at enabling the users to dynamically compose and interconnect their own operational environments and processes in a very simple and flexible fashion. In our talk, we will elaborate in detail on how the significant changes of the IT Industry affect stakeholders (resource providers, consumers and intermediaries), applications (types, development, management) and infrastructure (interfaces, composition, protocols). We further present the most related research projects carried out at the SAP Research Campus-based Engineering Center in St. Gallen, Switzerland.

    A new kind of Web-based application, known as Enterprise Mashups, has been gaining momentum in the last years. Enterprise Mashups implicate a shift concerning a collaborative software development and consumption process. End users combine and reuse existing Web-based resources within minutes to new value added applications in order to solve an individual and ad-hoc business problem. Novel design principles are currently about to emerge allowing to cover the long tail of user needs. In this position paper, we introduce the terminology used in context of this new paradigm and present an Enterprise Mashup Stack which consists of three layers: Web-based resources, widgets, and Mashups. Based on this model, we elaborate on the design principles of upcoming intermediaries and the mass collaboration form, the lightweight composition style as well as the perpetual beta development model. By means of the EU funded research project FAST, we show their real-world applicability. http://www.km-conference2009.org/workshops/KSM09.php

    We observe a huge demand for situational and ad-hoc applications desired by the mass of business end-users that cannot be fully implemented by IT departments. This is especially the case with regard to solutions that support infrequent, situational, and ad-hoc B2B scenarios. End users are not able to implement such solutions without the help of developers. Enterprise Mashup-/ and Lightweight Composition approaches and tools are promising solutions to unleash the huge potential of integrating the mass of end users into development and to overcome this "long-tail" dilemma. In this work, we summarize different patterns on how to realize B2B collaborations between different Mashup platforms. We also evaluate cloud computing infrastructures available on the Web as they might be a suitable platform for B2B integration via Mashups. As a major result, we provide an overview and first results of an architecture and implementation of a prototype that implements an API for Enterprise Mashup integration services. This prototype is built on the basis of different existing cloud infrastructures and services.

    The transfer of the mashup paradigm in corporate environments needs additional capabilities beyond those typically associated with consumer mashups. In this paper, we present the architecture of the FAST platform which allows creating enterprise-class and multi-channel visual building blocks (so called gadgets) in an ad-hoc manner. The design of complex enterprise-class gadgets is supported by an integrated semantic concept which hides the complexity from the actual users. The architectural components of the platform, a technical life cycle model for enterprise mashups, and the FAST gadget ontology are presented. By means of a cross-organizational real-world scenario from the marketing/ promotion event area, we demonstrate the value and potential of the FAST platform. http://www.icsoc.org/

    The huge demand for ad-hoc and situational enterprise-class applications led to a new kind of Web-based applications, known as enterprise mashups. End users from the business units with no programming skills are empowered to combine and reuse existing company internal and external resources within minutes to new value added applications. In order to handle the growing number of mashable components, we propose a context-aware concept for enterprise mashups that supports users to find relevant components according to their current situation and to compose them automatically. The designed context model which is structured in the three domains agent, computing and environment is implemented in the SAP Research RoofTop Marketplace prototype to demonstrate its applicability and business benefits.

    Business Benefits of Enterprise Mashups
    (2010-08-12)

    Giessmann, Andrea
    Enterprise mashup is a new development paradigm which empowers users from the business units to create individual applications without the involvement of the IT department. Unlike the service-oriented architecture paradigm, which allows the automation of structured business processes, enterprise mashups represent a technology of the next corporate technology adoption wave characterized by the peer production philosophy. It enables the automation of unstructured processes relevant for knowledge workers which could not be modeled in advanced. An open and unaddressed question in the scientific community is the discussion of the benefits of this new paradigm. This poster closes this gap by presenting a benefit model. We leverage the balance scorecard concept to structure and identify the benefits items from a holistic point of view. By means of a case study and an organized laboratory experiment, we demonstrate the applicability of the benefit model and quantify the benefits.

    Currently available solutions on the market addressing enterprise needs for Business to Business (B2B) integration have certain disadvantages, which includes the need of developers to implement B2B collaborations or the time needed to implement or change such integration projects. Enterprise Mashups, a new generation of Web-based applications which integrates users from the business units with limited programming skills in the development process, can address some of those issues. This paper presents a novel pattern which can be used to support cross-organizational integration by using the Enterprise Mashup paradigm together with Mashup integration services. This pattern is demonstrated by an implemented prototype which was evaluated by means of a sample scenario.

    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. Conference: http://conferences.computer.org/scc/2008/ Services now account for more than half of the U.S. economy. Services Computing, as a new cross discipline, addresses how to enable IT technology to help people perform business services more efficiently and effectively. Building on its great success in 2004, 2005, 2006, 2007, the 2008 IEEE International Conference on Services Computing (SCC 2008) continues to bridge the gap between Services Computing and Business models with an emerging suite of ground-breaking technology that includes service-oriented architecture (SOA), business process integration and management, services engineering and grid/utility computing, and Web 2.0. The theme of SCC 2008 is "Services: Business, Technology, and Application". From the technology foundation perspective, Services Computing has become the default discipline in the modern services industry. SCC 2008 will be co-located with and strategically part of the 2008 IEEE Congress on Services (SERVICES 2008) to explore "Services" (Science and Technology), which has been formally promoted by IEEE Computer Society since 2003! IEEE Services Oriented Architecture (SOA) Industry Summit, IEEE International Services Computing Contest, IEEE SOA Standards Symposium, IEEE Services Computing Workshops, IEEE Services Computing Ph.D. Student Symposium will be featured at this joint event in Hawaii, USA. Services Computing, as a new cross discipline, addresses how to enable IT and computing technology to help people perform business processes, services, and applications more efficiently and effectively. At the core of a business model is a set of processes that jointly help yield a profit in an organization. As we can see, Services Computing currently shapes the thinking of business modeling, business consulting, solution creation, service delivery, and software architecture design, development and deployment. The global nature of Services Computing leads to many opportunities and few challenges and creates a new networked economic structure for supporting different business models. SCC 2008 has the following major research tracks: Foundations of Services Computing, Services-Centric Business Models, Business Process Management and Integration, and SOA Tools, Solutions and Services. SCC 2008 is sponsored by the IEEE Computer Society Technical Committee on Services Computing. SCC 2004 was held in Shanghai, China, September 15-18, 2004 . SCC 2005 was co-located with ICWS 2005 on July 11-15, 2005 in Orlando, Florida, USA. SCC 2006 was co-located with ICWS 2006 on September 18-22, 2006 in Chicago, Illinois, USA. SCC 2007 was co-located with ICWS 2007 on July 9-13, 2007 in Salt Lake City, Utah, USA. The SCC Proceedings have been included in EI Compendex. SCC 2008 will concentrate on the science and technology of Business/Application Services and the bridging technologies such as Business Strategy and Design, Business Process Integration and Management, Grid and Utility Computing, and SOA Services and Solutions; while ICWS 2008 will continue to put its focus on all aspects of Web services from Computer Science and Engineering perspectives.
