    We present a goal-driven approach to model a choreographer for realizing composite Web services. In this framework, the users start with an abstract, and possibly incomplete functional specification of a desired goal service. This specification is used to compose a choreographer that allows communication between the client and the set of available component services, and is functionally equivalent... View full abstract»

    Current Web service composition languages like WS-BPEL require in-depth knowledge of these languages by the service composition designers. In this paper we present a high-level, visual service creation environment (SCE). This SCE provides service composition templates, verification of compatibility and guidelines, and advanced separation of concerns through aspect-oriented software development. Co...

    Web service compositions in BPEL have several nonfunctional requirements such as security, reliable messaging, and transactions. Although many WS-* specifications address such non-functional concerns in the Web service context, they focus only on the messaging-level requirements without addressing the process-level requirements. In this paper, we discuss different non-functional requirements in BP... View full abstract»

    Dynamic and self-organizing systems like those found in ubiquitous computing or semantic Web based scenarios raise numerous challenges regarding trust and privacy. Service discovery is a basic feature of SOA deployment in such systems, given that entities need to locate services they can describe but that they do not necessarily know. PKI based solutions to securing this mechanism, which require a... View full abstract»

  • A Multimedia-Specific Approach to WS-Agreement

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (327 KB) | HTML iconHTML

    WS-agreement offers a general language and protocol to establish agreements between two parties. In principle, this generality enables a wide variety of domains to be covered. Yet, agreement terms need to be developed for each domain, to allow specific requirements to be expressed. When addressing a domain, one can either invent new agreement terms, or leverage on existing approaches. This paper p... View full abstract»

    Interoperability in a large-scale distributed system is challenged by the diversity of node policies. We introduce AMPol (adaptive messaging policy), a service-oriented architecture that facilitates policy-aware, end-to-end adaptive messaging between multiple parties. AMPol provides services for expressing non-functional QoS policies, finding them, and carrying out system extensions to adapt to th... View full abstract»

  • Composing Web Services with PEWS: A Trace-Theoretical Approach

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (229 KB) | HTML iconHTML

    PEWS is an interface description language for both individual and composed Web services. Individual Web services are expressions over WSDL-defined operations while composed Web services are expressions over PEWS-defined services. This paper distinguishes two dimensions of PEWS. The control dimension describes the control workflow of the service, i.e. the order in which the operations of the Web se... View full abstract»

    During the past few years, Web services composition has been one of the ongoing research activities in the software engineering area. It is simply defined as finding a composition of available Web services that provides a requested behavior. In this paper, we study this problem for stateless Web services; i.e., Web services with a two-step workflow: receiving some inputs and returning some outputs... View full abstract»

  • Fast Quality Driven Selection of Composite Web Services

    The composite Web service selection is the process of building an executable composite Web service. Generally, the selection process involves decision making in terms of non-functional properties of Web services such as QoS requirements. Since the number of Web services is rapidly increasing and the QoS of the Web services environment changes dynamically, the fast selection is important. This pape... View full abstract»

    In this paper we present a platform for the direct consumption of Web services by a Mobile Station. We give an architectural solution where Mobile Operators play the role of Trusted Third Parties supplying service credentials that allow a co-located 3GPP network application function and liberty-enabled identity provider entity to implement a controlled shopping mall service to mobile stations from...

    Business transactions in Web service environments run with relaxed isolation and atomicity property. In such environments, transactions can commit and roll back independently on each other. Transaction management has to reflect this issue and address the problems which result for example from concurrent access to Web service resources and data. In this paper we propose an extension to the WS-trans... View full abstract»

    Web services have emerged as a key technology that enables interoperability between distributed applications. It is desirable that SOAP, being the Web service transport protocol for interconnecting applications across organizations, performs efficiently in environments where there are a large number of transactions. This paper presents a novel approach to address this issue and hence improve Web s... View full abstract»

    A broader use of e-services for cross enterprise collaboration requires the services to be analysed and designed with a clear business focus. From a business perspective, the e-services must support the primary values that an organization strives for. From an operational perspective, the e-services must be devised such that they support the day-to-day activities in the business. In this paper, we ... View full abstract»

    The service-oriented architecture (SOA) has attracted lots of attentions these days. However, SOA is essentially a design methodology that has existed for decades, and doesn't provide enough details about the development, reuse and integration of the services. The Business Process Execution Language for Web services (BPEL4WS) has offered a formal specification for integrating loosely coupled servi... View full abstract»

    Loose coupling is often cited as a defining characteristic of service-oriented architectures. Interactions between services take place via messages in an asynchronous environment where communication and processing delays can be unpredictable; further, interacting parties are not required to be on-line at the same time. Despite loose coupling, many service interactions have timing and validation co... View full abstract»

    In this paper, we present an approach to hybrid semantic Web service matching based on both logic programming, and syntactic similarity measurement. The implemented matchmaker, called WSMO-MX, applies different matching filters to retrieve WSMO-oriented service descriptions that are semantically relevant to a given query with respect to seven degrees of hybrid matching. These degrees are recursive... View full abstract»

    The automated composition of Web services is one of the most promising ideas and at the same time one of the most challenging research area for the taking off of service-oriented applications. It is widely recognised that one of the key elements for the automated composition of Web services is semantics, i.e. unambiguous descriptions of Web services capabilities and processes. However Web services... View full abstract»
