“…Another possible solution would be BPEL light [26], which addresses the tight coupling of the abstract and concrete part. BPEL light completely disposes of WSDL and aims at only specifying message exchange patterns, which then need to be matched to arbitrary interface descriptions at runtime.…”

Fine-Grain Interoperability of Scientific Workflows in Distributed Computing Infrastructures

Today there exist a wide variety of scientific workflow management systems, each designed to fulfill the needs of a certain scientific community. Unfortunately, once a workflow application has been designed in one particular system it becomes very hard to share it with users working with different systems. Portability of workflows and interoperability between current systems barely exists. In this work, we present the fine-grained interoperability solution proposed in the SHIWA European project that brings together four representative European workflow systems: ASKALON, MOTEUR, WS-PGRADE, and Triana. The proposed interoperability is realised at two levels of abstraction: abstract and concrete. At the abstract level, we propose a generic Interoperable Workflow Intermediate Representation (IWIR) that can be used as a common bridge for translating workflows between different languages independent of the underlying distributed computing infrastructure. At the concrete level, we propose a bundling technique that aggregates the abstract IWIR representation and concrete task representations to enable workflow instantiation, execution and scheduling. We illustrate case studies using two real-workflow applications designed in a native environment and then translated and executed by a foreign workflow system in a foreign distributed computing infrastructure.

“…Therefore, for an automatic transition t starting at state s we just need to translate its associated time conditions into T B as the (logical) conjunction of the time conditions for t and the conjunction of the negation of the time conditions associated to any other automatic transition originating at s whose transition identifier is smaller than t. 5 The resulting ETA is deterministic. The language of T B is, by construction, exactly R B (see Section 2.3).…”

“…Recently, a simplified version of BPEL 2.0, called BPEL Light [5], has been proposed to encode complex, executable MEPs. BPEL Light extends BPEL 2.0 with a WSDL-less interaction model that makes it possible to specify processes representing orchestration-based MEPs independently from Web service technologies.…”

Abstract. Service networks comprise large numbers of long-running, highly dynamic complex end-to-end service interactions reflecting asynchronous message flows that typically transcend several organizations and span several geographical locations. At the communication level, service network business protocols can be flexible ranging from conventional inter-organizational point-to-point service interactions to fully blown dynamic multi-party interactions of global reach within which each participant may contribute its activities and services. In this paper we introduce a formal framework enriched with temporal constraints to describe multiparty business protocols for service networks. We extend this framework with the notion of multi-party business protocol soundness and show how it is possible to execute a multi-party protocol consistently in a completely distributed manner while guaranteeing eventual termination.

“…Thus, in this paper we do not rely upon the presence of a specific description language. Similar to the BPEL simplification presented in [18], our approach is independent from the chosen service description language. We propose BPEL extensions that directly map to the resource abstraction and natively support the corresponding interaction mechanisms and invocation patterns [19].…”

RESTful Web service composition with BPEL for REST

a b s t r a c tCurrent Web service technology is evolving towards a simpler approach to define Web service APIs that challenges the assumptions made by existing languages for Web service composition. RESTful Web services introduce a new kind of abstraction, the resource, which does not fit well with the message-oriented paradigm of the Web service description language (WSDL). RESTful Web services are thus hard to compose using the Business Process Execution Language (WS-BPEL), due to its tight coupling to WSDL. The goal of the BPEL for REST extensions presented in this paper is twofold. First, we aim to enable the composition of both RESTful Web services and traditional Web services from within the same process-oriented service composition language. Second, we show how to publish a BPEL process as a RESTful Web service, by exposing selected parts of its execution state using the REST interaction primitives. We include a detailed example on how BPEL for REST can be applied to orchestrate a RESTful e-Commerce scenario and discuss how the proposed extensions affect the architecture of a process execution engine.
