Service-oriented Distributed Applications in the Future Internet: The Case for Interaction Paradigm Interoperability

International audienceThe essential issue of interoperability in distributed systems is becoming even more pressing in the Future Internet, where complex applications will be composed from extremely heterogeneous systems. Open system integration paradigms, such as service oriented architecture (SOA) and enterprise service bus (ESB), have provided answers to the interoperability requirement. However, when it comes to integrating systems featuring heterogeneous interaction paradigms, such as client-service, publish-subscribe and tuple space, existing solutions are typically ad hoc and partial, applying to specific interaction protocol technologies. In this paper, we introduce an interoperability solution based on abstraction and merging of the common high-level semantics of interaction paradigms, which is sufficiently general and extensible to accommodate many different protocol technologies. We apply this solution to revisit the SOA- and ESB-based integration of heterogeneous distributed systems

Semantic service matchmaking in the atm domain considering infrastructure capability constraints

In a service-oriented environment business processes flexibly build on software services provided by systems in a network. A key design challenge is the semantic matchmaking of business processes and software services in two steps: 1. Find for one business process the software services that meet or exceed the BP requirements; 2. Find for all business processes the software services that can be implemented within the capability constraints of the underlying network, which poses a major problem since even for small scenarios the solution space is typically very large. In this chapter we analyze requirements from mission-critical business processes in the Air Traffic Management (ATM) domain and introduce an approach for semi-automatic semantic matchmaking for software services, the System-Wide Information Sharing (SWIS) business process integration framework. A tool-supported semantic matchmaking process like SWIS can provide system designers and integrators with a set of promising software service candidates and therefore strongly reduces the human matching effort by focusing on a much smaller space of matchmaking candidates. We evaluate the feasibility of the SWIS approach in an industry use case from the ATM domain. Document type: Part of book or chapter of boo

Seamless integration of cyber-physical systems in knowledge graphs

Cyber-Physical Systems (CPS) are engineering systems that result from the integration of both physical and computational components designed from different engineering perspectives. Standards addressing smart manufacturing, such as AutomationML, can be used to describe CPS components and to facilitate their integration. Albeit expressive, these standards allow for the representation of the same features in various ways, thus hampering a fully integrated description of CPS components. We tackle this integration problem and propose SemCPS, a framework able to combine Probabilistic Soft Logic and Knowledge Graphs to semantically describe a CPS and its components. We evaluated SemCPS on a set of testbeds of AutomationML documents describing CPS components from various perspectives. Results sug gest that SemCPS enables not only the seamless integration of CPS components but also allows for preserving individual characteristics of these components
