{"title":"Tutorial session services oriented architecture and semantic web processes","authors":"F. Curbera, A. Sheth, Kunal Verma","doi":"10.1109/ICWS.2004.1314712","DOIUrl":"https://doi.org/10.1109/ICWS.2004.1314712","url":null,"abstract":"This tutorial presents what can be achieved by symbiotic synthesis of two of the hottest R&D and technology application areas: Web services and the Semantic Web. It presents the more recent evolution of the Web service platform towards rich Web service and process model annotation, and explores some of the promises and challenges in applying semantics to each of the steps in the Semantic Web Process lifecycle. In particular, we present current Web services directions and the role of semantics in annotation (Semantic Annotation of Web Services), discovery (Semantic Web Service Discovery), composition (Semantic Web Process Composition), process execution/enactment (Semantic Web Process Orchestration), and quality of service of Semantic Web Processes. We also review ongoing frameworks and initiatives such as Semantic Web Service Initiative Architecture Committee (SWSA) [1], Semantic Web Services Language (SWSL) [2] and OWL-S [3], as well as results from key projects such as the METEOR-S [4] which build upon research, technology and current standards in workflow processes, Semantic Web, Web services and simulation.

However, while industry standards for the description, composition, and orchestration of Web services have been under discussion (and development) for quite some time already, their conceptual underpinnings are still in their infancy. Indeed, conceptual models/or service specification are rare so far, as are investigations based on them. This paper presents a multilevel service composition model that perceives service specification as going through several levels of abstraction, from transactional operations to the end user. Importantly, the model allows for specification of desirable composition properties at all levels. Different ways of achieving these properties as well as implications of the model are addressed.","PeriodicalId":135986,"journal":{"name":"Proceedings.

The main challenge is the development and support of runtime cross-standard service activation and interoperation. Such interoperation will provide a vital stepping-stone towards the integration of the emerging SOA standards and legacy services - those developed using existing middleware architectures such as DCOM, CORBA, J2EE, Web service, JXTA, and Jini. Much related works already exist including WSIF framework, which provides APIs to support design-time invocation of cross-standard Web services deployed on multiple SOAP packages. However, this paper focuses on a runtime self-regenerative mechanism related to adaptive service invocation code. The paper will present a runtime service adaptation mechanism, which supports end-users to dynamically adapt to variations in the execution environment, without altering their original design, crossing multiple standards (both synchronous and asynchronous invocation models) and middleware architectures. This paper also introduces a proposed \"Polyarchical Middleware\" architecture to support such self-regenerative service adaptation. An illustrative example will be used to describe the approach and the current implementation. The paper will conclude with general remarks and mention of further work.","PeriodicalId":135986,"journal":{"name":"Proceedings.

Even though there are massive Web services specifications development underway, early adoption by developers and tool vendors is becoming a need. The potential growth of this technology is highly predictable because of its universal acceptance and use among the developer community. This industry may expect to grow enormously based on the support from various communities that benefit from this technology. Researches are carried out in various standards bodies on various aspects of Web services such as definition, architecture, security, discovery, interoperability, etc. As we are committed to the success of this technology, we need to research on service oriented containers that makes Web services potential more constructive. This paper proposes a container for Web services which can manage and monitor the state and behavior of Web services, which may address the quality of service (QoS) factor for Web services.","PeriodicalId":135986,"journal":{"name":"Proceedings.

The portal design demonstrates that flexibility, reusability and interoperability can be provided for both end users and portal developers by using semantic Web services technologies.","PeriodicalId":135986,"journal":{"name":"Proceedings.

Most Web services are stateful, such as services for business processes, and they converse with each other via properly ordered interactions, instead of individual unrelated invocations. In order to address efficient integration of conversational Web services, we create a unified specification model for both conversation protocol and composition; we propose methods to integrate a partner service with complex conversation protocol into a composition of Web services; assure the correctness of composition by formal verification. The mapping between our model and BPEL4WS is also discussed.","PeriodicalId":135986,"journal":{"name":"Proceedings.

In this paper, we present an algorithm and a prototype for the automatic composition of Web services that implement workflows described in a high level language. Our approach has many advantages comparing to the manual creation of a simple program composition, such as smaller implementation time and cost, reliability with the generation of contingency plans, greater capacity to evolve with the dynamic service discovery, and faster execution time with the use of heuristics. We use the OWLS ontology to semantically describe Web services metadata and indexes to help selecting them. The proposed algorithm considers that equivalent services may have different interfaces and also respects preferences of the users.","PeriodicalId":135986,"journal":{"name":"Proceedings.

It builds upon recent standardization efforts related to Web services.

General concepts and standards like SOAP, WSDL, and UDDI support the discovery and invocation of single Web services. State-of-the-art process management is conceptually based on a centralized process manager. The resources of this coordinator limit the number of concurrent process executions, especially since the coordinator has to persistently store each state change for recovery purposes. In this paper, we overcome this limitation by executing processes in a peer-to-peer way exploiting all nodes of the system. By distributing the execution and navigation costs, we can achieve a higher degree of scalability allowing for a much larger throughput of processes compared to centralized solutions. This paper describes our prototype system OSIRIS, which implements such a true peer-to-peer process execution. We further present very promising results verifying the advantages over centralized process management in terms of scalability.","PeriodicalId":135986,"journal":{"name":"Proceedings.
