Online workflow repositories let scientists share successful experimental routines and compose new workflows from best practices and existing service components. The authors share the results of a social network analysis of the myExperiment workflow repository to assess the state of scientific workflow reuse and propose the CASE framework to facilitate such reuse.
In scientific collaboration platforms such as caGrid, workflow-as-a-service is a useful concept for various reasons, such as easy reuse of workflows, access to remote resources, security concerns, and improved execution performance. We propose a solution for facilitating workflow-as-a-service based on Taverna as the workflow engine and gRAVI as a service wrapping tool. We provide both a generic service...
Scientific communities are increasingly exposing information and tools as online services in an effort to abstract complex scientific processes and large data sets. Clients are then able to access services without knowledge of their internal workings therefore simplifying the process of replicating scientific research. Taking a service-oriented approach to science (SOS) facilitates reuse, extension,...
Service-oriented architecture represents a promising approach to integrating data and software across different institutional and disciplinary sources, thus facilitating Web-scale collaboration while avoiding the need to convert different data and software to common formats. The US National Cancer Institute's Biomedical Information Grid program seeks to create both a service-oriented infrastructure...
With the emergence of global market and virtual enterprises, coordination of business processes in dispersed organizations by distributed workflow execution will take on more importance. At the same time, grid workflow is now been regarded as a fundamental service in grid environment. In this paper we give a real life example to see how distributed workflow technology can be used in virtual enterprises...
The evolution of grid technologies has brought to the world a loosely coupled environment that enables flexible integration among heterogeneous systems. On building a service-oriented architecture for grid systems, more and more research is focused on service composition, in which workflow and simulation techniques have shown great potential. Simulation of services' interaction is important since...
