Texo: Wie Theseus das Internet der Dienste Gestaltet — Perspektiven der Verwertung

Das Internet hat in den letzten zwei Jahrzehnten eine Reihe radikaler Aderungen in Gesellschaft und Wirtschaft mit sich gebracht. Die erste Welle bezog sich auf den Umgang mit wissenschaftlichen Publikationen und Daten. Das World Wide Web revolutionierte die Art, wie Dokumente und Informationen dargestellt und ausgetauscht wurden. In einer folgenden Welle entstanden einfache kommerzielle Systeme. In den Web Shops und Verkaufsplattformen wurden Kommoditaten wie Bucher, Musik CDs oder gebrauchte Gegenstande gehandelt. Auch erste Ansatze fur geschaftliche Prozesse zwischen Unternehmen — beispielsweise in der Beschaffung — wurden realisiert.

Diversified Service Provisioning in Global Business Networks

Companies and their services are being increasingly exposed to global business networks and Internet-based on-demand services. Much of the focus is on flexible orchestration and consumption of services, beyond ownership and operational boundaries of services. However, ways in which third-parties in the global village can seamlessly self-create new offers out of existing services remains open. This paper proposes a framework for service provisioning in global business networks that allows an open-ended set of techniques for extending services through a rich, multi-tooling environment. The Service Provisioning Management Framework, as such, supports different modeling techniques, through supportive tools, allowing different parts of services to be integrated into new contexts. Integration of service user interfaces, business processes, operational interfaces and business object are supported. The integration specifications that arise from service extensions are uniformly reflected through a kernel technique, the Service Integration Technique. Thus, the framework preserves coherence of service provisioning tasks without constraining the modeling techniques needed for extending different aspects of services.

Enabling USDL by Tools

Fundamental tooling is required in order to apply USDL in practical settings. This chapter discusses three fundamental types of tools for USDL. First, USDL editors have been developed for expert and casual users, respectively. Second, several USDL repositories have been built to allow editors accessing and storing USDL descriptions. Third, our generic USDL marketplace allows providers to describe their services once and potentially trade them anywhere. In addition, the marketplace software can be customized to different settings and considers the idiosyncrasies of service trading as opposed to the simpler case of product trading. The chapter also presents several deployment scenarios of such tools to foster individual value chains and support new business models across organizational boundaries.We close the chapter with an application of USDL in the context of service engineering.

Semantic-Based Case Retrieval of Service Integration Models in Extensible Enterprise Systems Based on a Business Domain Ontology

In spite of the advances in Service-Oriented Computing (SOC), the extension of standard enterprise systems with complementary services provided by third-party vendors still requires deep expert knowledge. However, valuable integration experience from similar problems already solved in the past is not systematically leveraged which leads to high integration costs. We tackle this problem by exploring Case-Based Reasoning techniques in this novel application context. A key challenge for the reuse of integration knowledge is to retrieve existing integration cases that have been developed in similar functional areas within the process space of standard enterprise systems. In this paper we present a Business Domain Ontology that provides a formal representation of reference processes in the domain of standard enterprise systems. In addition a case retrieval algorithm is proposed, that computes the similarity between two integration cases based on the semantic distance between concepts within the Business Domain Ontology.
