We explore the notion of the workflow for specifying interactions among collections of devices (which we term device ecologies). We discuss three levels of abstraction in programming device ecologies: high-level workflow, low-level workflow and device conversations, and how control (in the sense of operations issued by an end-user on such workflows or exceptions) is passed between levels. Such ...

In the past few years there has been an increasing interest in distributed workflow management technology for the requirement of supporting business process in modern corporations. As the process in large enterprise tends to be across many branches which are distributed over a wide geographic area and have their own IT infrastructures, the current workflow management systems do not have suffici...

The specification of business processes is becoming a more and more critical aspect for organizations. Such processes are specified as workflow models expressing the logical precedence among the different business activities (i.e. the units of work). Up to now, workflow models have been commonly managed through specific subsystems, called workflow management systems. In this paper we advocate f...

In this paper, we present a Workflow-based grId portal for problem Solving Environment(WISE) which has been developed by integrating workflow, Grid and web technology to provide an enhanced powerful approach for problem solving environment. Workflow technology supports coordinated execution of multiple application tasks on Grid resources by enabling users to describe a workflow by composing man...

Across many fields of science, primary data sets like sensor read-outs, time series, and genomic sequences are analyzed by complex chains of specialized tools and scripts exchanging intermediate results in domain-specific file formats. Scientific workflow management systems (SWfMSs) support the development and execution of these tool chains by providing workflow specification languages, graphic...

This paper introduces MELOGRAPH, a new system that exposes in the front-end a domain specific language(DSL) for graph processing tasks and in the back-end identifies, ranks and generates source code for the top-N ranked engines. This approach lets the specialized MELOGRAPH be part of a more general multi-engine workflow optimizer. The candidate execution engines are chosen from the contemporane...

ebXML is becoming the new international standard for the specification and deployment of complex B2B transactions over the internet. ebXML transactions are inherently distributed, involving many actors exchanging XML messages with each other according to complex flows and rules. This complexity hampers validation of the correctness of a modelled business transaction by business experts. To alle...
