Business models and information systems for sustainable development

Businesses are expected to explore market opportunities in the area of sustainable development, thus contributing to finding solutions aiming at sustainable quality of life. This will require adaptation and innovation of business models and information systems, with challenges of particular interest to the business modeling and software design community. This paper briefly discusses two relevant topics in this respect, namely (i) goal and value modeling, and (ii) model-driven development. We mention existing work that can be taken as a starting point for addressing sustainability issues, and we make some observations that may be taken into account when extending existing work

WSCDL to WSBPEL: A Case Study of ATL-based Transformation

The ATLAS Transformation Language (ATL) is a hybrid transformation language that combines declarative and imperative programming elements and provides means to define model transformations. Most transformations using ATL reported in the literature show a simplified use of ATL, and often involve a single transformation. However, in more realistic situations, multiple transformations may be necessary, especially in case the original input/output models are not represented in the metametamodeling representation expected by the transformation engine. In this paper, we discuss a model transformation from service choreography (WSCDL) to service orchestration (WSBPEL), which cannot be performed in a single ATL transformation due to the mismatch between the concrete XML syntax of these languages and the metametamodeling representation expected by the ATL transformation engine. This requires auxiliary transformations in which this mismatch is resolved. In principle, the required auxiliary transformations can be implemented using XSLT or a general-purpose programming language like Java. However, in our case study, we evaluate the use of ATL to perform these transformations. We exploit ATL by leveraging the ATL's XML\ud injection and the XML extraction mechanisms to perform the overall transformation in terms of a transformation chain

An Evaluation Of Service Frameworks For The Management Of Service Ecosystems

A service ecosystem is a marketplace for trading services in which services are developed, published, sold and used. Service ecosystems have changed the way of service delivery and service consumption among actors/parties, who perform specific roles for the operation of the ecosystems. Such actors, being service providers, consumers, mediators and intermediaries, ensure the livelihood of the ecosystem. However, the role of the service infrastructure provider, one of the actors of the service ecosystem, is still not being explored sufficiently. The service infrastructure provider provides service infrastructures/frameworks upon which other actors of the service ecosystem operate. In this paper, an evaluation framework for the service framework is defined, which is based on the features that are required for a service ecosystem to thrive. The evaluation framework is used to evaluate three opensource service frameworks. The evaluation framework facilities the selection process of a service framework among the largely available ones

Cooperation Patterns and Adaptation Patterns for Service-Based Inter-Organizational Workflows

International audienceModernization is an effective approach to making existing mainframe and distributed systems more responsive to business needs. SOA (service-oriented architecture) is an adequate paradigm that allows companies to tap into the business value in their current systems and position IT for rapid future changes to the business model. In our research works, we focus on the use of SOA to implement Inter- Organizational WorkFlows (IOWF). The goal is to take benefits from the advantages offered by the SOA paradigm like interoperability, reusability and flexibility in order to deal with workflow models easily adaptable, evolvable and reusable. This paper focuses on two specific architectures of IOWF which are the "chained execution" and the "subcontracting"; the first issue of this work is to define Service-Based Cooperation Patterns (SBCP) suitable to the two architectures considered. A SBCP is based on SOA; it is defined through three main dimensions: the distribution of services among the partner's sites, the control of instance execution and the structure of interaction between the workflows involved in the cooperation. The second issue of the paper consists of adaptation and evolution of IOWF process models obeying to the defined SBCP. Then, we state the main operations of adaptation that can be applied on these models; we focus on adaptation at process and interactional levels. Conformably to the three dimensions of SBCP, we define three classes of adaptation patterns: "service adaptation", "control flow adaptation" and "interaction adaptation" patterns. Also, we particularly distinguish some operations of adaptation called evolution of process models based on two perspectives: the expansion of the global functionality of the process and the expansion of the cooperation; we show that some evolutions are realized by reuse of existing IOWF models. For implementation, we consider IOWF process models specified with BPEL

Model-driven development of service compositions for enterprise interoperability

Service-Oriented Architecture (SOA) has emerged as an architectural style to foster enterprise interoperability, as it claims to facilitate the flexible composition of loosely coupled enterprise applications and thus alleviates the heterogeneity problem among enterprises. Meanwhile, Model-Driven Architecture (MDA) aims at facilitating the development of distributed application functionality, independent from its implementation using a specific technology platform and thus contributes to deployment in different platforms. In this paper we propose an MDA-based transformation technique for service composition. The contribution of the paper is two-fold. First, our approach shows how enterprise interoperability is supported by service composition at two different technical levels, namely at choreography and orchestration level. Second, the approach contributes to the management of changes that affect enterprise interoperability, by defning a (semi-)automated transformation from choreography to orchestrations in which the interoperability constraints specified at the choreography level are preserved
