    During the last years, electronic collaboration between enterprises has significantly increased. To seamlessly integrate applications across company boundaries, all stakeholders have to adhere to common standards. Currently, cross-organizational business relationships are setup based on a plethora of standards that involve different technical representations, semantics, process specifications and also vary with respect to scope and granularity. The resulting business standards dilemma prevents corporations from seamlessly cooperating with each other. State-of-the-art standards tackle parts of this interoperability issue by providing flexible and semantically more precise specifications, but have not yet been widely adopted. The abundance of different standards, but also the frequently divergent interests of stakeholders involved in the development and adoption of standards prevents enterprises from seamlessly interconnecting their applications. In this work, we leverage institutional economics to elaborate on a novel approach to facilitating enterprise interoperability. Not the creation of yet another standard, but the establishment and fostering of a proper institutional framework will significantly reduce the stakeholders' uncertainty in deciding for and adopting a standard and thus drive seamless cross-organizational interoperability. A key outcome of the ATHENA-project, the Enterprise Interoperability Center (EIC) is expected to provide such an institutional framework. This work is devoted to analyzing this center on the basis of institutional economics in order to derive essential recommendations for it to emerge as the prevailing reference point for e-Business standards and to thus accelerate the seamless and efficient electronic collaboration between enterprises. https://admin.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/webcontent/uuid/d0ab69b4-9037-2a10-989c-f496bd451695

    Web Services have experienced great interest during the last years as they are expected to act as enablers of seamless application-to-application integration both within company boundaries and on a global scale. Especially the automation of cross-organizational, information intensive business processes through the loose composition of standardized services is believed to significantly reduce costs and increase operational agility. In this work, we present three different strategies to supporting Web Service composition across corporate boundaries: A central service orchestration architecture, a hybrid orchestration approach with hub support and finally a fully decentralized orchestration solution without any central control entity. We evaluate and compare the three strategies on the basis of the eight criteria functional scope, monitoring capabilities, fault detection and removal, simultaneousness of process instance execution, scalability, security, seamless interoperability of the coupled applications as well as end-point complexity. The analysis shows that the hybrid approach represents the most promising solution as it unifies the advantages of centralized and decentralized strategies. www.sysedv.tu-berlin.de/SemSoc/ http://www.icsoc.org/

    Advancing Interoperability for Agile Cross-Organisational Collaborations: A Rule-Based Approach
    (IGI-Global, 2010)
    Gionis, George
    ;
    Schroth, Christoph
    ;
    Janner, Till
    Gionis, Schroth and Janner present a comprehensive Model-Driven Architecture for enabling agile cross-organisational collaboration, in an international context, by integrating business and legal rules in private and collaborative processes, business documents and their resulting service orchestrations. The resulting framework, that was mostly developed and applied in the course of the EU-funded research project GENESIS, ranges from graphical process and data models and declarative rule structures to the technical specification of a hybrid software architecture for integrating rule with process and data models.

    The dawn of the XML era appears insufficient to guarantee a holistic approach in electronic transactions, as long as the semantics confusion, the lack of a common understanding of the underlying data and the business standards dilemma prevail and prevent data interoperability issues from being resolved. As various e-Government initiatives are being realized throughout the world, an imperative need for creating unified governmental data models that will facilitate the seamless exchange of information and the deployment of interoperable systems in Enterprises and Central, Regional and Municipal Government emerges. After attempting to identify relevant research that has been undertaken in the field of data modeling, the present paper analyzes the scope and the objectives of the business information modeling oriented towards governmental data. Based on UBL (Universal Business Language) and CCTS (Core Components Technical Specification), a component-based data modelling methodology enhancing business-to-government interoperability is proposed, creating the basis for a repository of governmental data models. The approach adopted may also serve as guidelines for creating and transitioning between "generic - harmonized" and "specific - contextualized" documents. A real world paradigm extracted from the Periodic VAT Statement document finally comes to prove the soundness of the proposed methodology. http://minbar.cs.dartmouth.edu/greecom/ejeta/specialMay08-issue.php http://minbar.cs.dartmouth.edu/greecom/ejeta/specialMay08-issue/ejeta-special-08may-4.pdf

    Modern e-Business frameworks have evolved from traditional EDI technology. The evolutionary development towards current e-Business stacks like RosettaNet led to an increased degree of integration and operational efficiency. Nevertheless, significant shortcomings still exist. Especially on the semantic level of data and process engineering further improvements are expected to harmonize the diversity and redundancy of existing e-Business stacks. UN/CEFACT's standardization efforts are a promising solution towards next generation e-Business frameworks. The authors intend to provide a picture of the future of e-Commerce by evaluating three cornerstones of e-Business standard evolution: EDI, RosettaNet and a novel combination of specifications issued by UN/CEFACT.

    Today electronic transactions constitute a constantly growing business reality that promises advantages such as reduced transactional cost, seamless information flow, and better communication and collaboration with business partners. However, the creation of a system clearly oriented towards promoting interoperability of existing systems and facilitating electronic transactions between partners of diverse nature, like enterprises and governmental bodies, still faces significant drawbacks such as the high technical complexity of the proposed solutions or the need for intervention of third-party systems in the transactions. Such problems can largely be attributed to the adopted architectures - primarily peer to peer and server based - that impose specific preconditions in the design and implementation of the systems. The present work is an attempt to define and justify a hybrid architecture that shares common elements with peer to peer and server based architectures and relies on emerging technologies and standards in order to achieve application to application interconnection and seamless information flow directly among heterogeneous systems. The approach implies the establishment of a server based environment that will provide all the necessary requirements for enterprise applications to interoperate, execute dynamic workflows and exchange business documents of different formats with applications and systems of other enterprises and governmental bodies.

    Today value creation is highly dependent on information and communication technology but also on cooperation between companies. The traditional value chain has been replaced by dynamic value networks. To support this new form of business, solutions for Enterprise Interoperability (EI) are indispensible. One possible form of solution constitutes EI platforms. To market them successfully adequate business models have to be found. Based on a business model framework this work evaluates factors that have to be considered in business models for EI platform providers. Moreover this work gives a concrete example of how a business model could look like in the concrete case of such a platform which is subject of the EU-funded research project GENESIS. In addition, possible implications are discussed.

    In this work, we propose a novel e-Business architecture that takes into account the specific needs of small and medium-sized enterprises (SMEs). The envisioned system supports collaborative and evolutionary modeling, semi-automatic negotiation and finally execution of business processes and ensures true interoperability through a common semantic repository. Potential business partners are enabled to easily retrieve each other and initiate business relations in an extremely intuitive manner. With the help of the Balanced Scorecard approach, we thoroughly investigate economic benefits SMEs will experience when participating at this system. The analysis highlights advantages regarding five different perspectives: SMEs may capitalize from reduced operating costs and improved gains (financial perspective), increased customer satisfaction and retention (customer perspective), faster and more efficient internal processes (internal working process perspective), improved supply chain integration (supply chain perspective), and technological advancements (system benefits).

    In this work, we propose an e-Business architecture that takes into account the specific needs of small and medium-sized enterprises (SMEs) and present a model-driven, highly flexible and collaborative approach that fosters cross-organizational interoperability. The specifications defined by the standardization body UN/CEFACT (e.g. UN/CEFACT Modeling Methodology, Core Component Technical Specification) and the ebXML standard are central composites of our novel holistic framework that aims at reducing effort required for performing business transactions. The introduction of methods for automatized business process and data negotiation is a further cornerstone of this work. http://www.ieeexplore.ieee.org/xpl/freeabs_all.jsp?isnumber=4400943&arnumber=4401016&count=149&index=72
