Grid environments enable collaborations involving large numbers of people and large scale resources, and promote the emergence of a new paradigm for scientific research: e-Science. Different layers of middleware, e.g., for managing Grid resources, computing tasks, data, and information, form the basic framework for realising an e-Science environment. By automating the management of experiment routines, a scientific workflow management system hides the underlying integration details of the e-Science resources and allows a scientist to focus on the high level domain specific aspects of the experiments. The support for scientific workflows is being recognised as a crucial feature for introducing an e-Science environment to application scientists from different domains.
The WSES workshop focuses on practical aspects of scientific workflow management systems: design, implementation, applications in all fields of computational science, interoperability among workflows and the e-Science infrastructure, e.g., knowledge framework, for workflow management. The workshop aims to provide a forum for researchers and developers in the field of e-Science to exchange the latest experience and research ideas on scientific workflow management and e-Science. Live demos of workflow systems and workflow application are welcome.

The second international workshop on Workflow Systems in e-Science (WSES 07) organized by Zhiming Zhao and Adam Belloum was successfully held in the context of International Conference of Computational Science (ICCS 2007) in Beijing in May 29 and 30, 2007. The first WSES event was held in ICCS 2006 in Reading University, UK. WSES07 attracted 31 submissions.† Each paper was reviewed by at least three referees, and 17 papers, including 10 regular ones and 7 short ones, were accepted. The presentations were organized as three sessions. In total, six speakers were not able to attend the workshop.
∑ Composing Different Models of Computation in Kepler and Ptolemy II: presented by Antoon Goderis. The talk gave an interesting insight on the problem of combining different computing models in hierarchical workflows, it turns out from this study that even if a system, e.g., Kepler,† supports different computing models, it does not always work or lead to a useful combination.
∑ WS-VLAM: A GT4 Based Workflow Management System. Presented by Adam Belloum. The talk describes the architecture of a distributed workflow management system. The proposed architecture is based on Web Service Resource Framework. In WS-VLAM, workflow composer and engine are loosely coupled, and other web service compliant workflow engines, e.g., Taverna, can be integrated in VLAM workflows.
∑ Distributed Applications from Scratch: Using GridMD Workflow Patterns: presented some requirements of† Molecular Dynamics and Monte-Carlo simulations application and proposed a solution to automate the generation of the workflow components using a C++ library.
∑ A Multi-agent System for Cross-Organizational Workflows Management Based on Process-View: addressed the interoperability across enterprises boundaries. And described the Process-view as a promising way to cross-organizational workflows design. The talk presented a multi-agent architecture combined with Petri net based process-view approach to facilitate cross-organizational workflows management.
∑ Toward Dynamic Adoption for a Userís Situation Information in a Context-Aware Workflow System presented by Yongyun Cho. The talk describes a context-aware workflow system for ubiquitous computing environments. The proposed systems supports dynamic changes of services at runtime without stopping the of workflow execution. The system uses DItree data structure to organize the tree information to achieve easy and fast dynamic changes.
∑ A Dataflow-Oriented Atomicity and Provenance System for Pipelined Scientific Workflows presented by Liqiang Wang, and Jeffrey Ram. The talk describes an architecture for scientific workflow management systems that supports both provenance and atomicity. The atomicity model supports the notions of commit/abort while the provenance model in addition to supporting existing provenance graphs and queries, also supports queries related to atomicity and failure.
Workflow Management for P2P Environments Using Agents
presented by Barros. The talk describes a P2P framework for dynamic workflows, which uses contracts to deal with unexpected changes in the flow of activities. The presented system provides adequate support for e-Science experiments defined as workflows, with tasks operating in distributed environments and diverse types of computational resources and data.
Grid Workflow System
presented by† Michal Laclavik, Zoltan Balogh, Ladislav Hluchy, and Ondrej Habala. The talk described a grid enabled workflow system on the semantic grid services. The proposed system allows abstract workflow composition and automatic creation of concrete workflows based on semantically enabled service discovery.† The semantic grid service model is based on the Web Service Resource Framework (WSRF) and the Web Service Ontology (OWL-S).
∑ Building Scientific Workflows for Earth System Modeling with Windows Workflow Foundation presented by Gang Xue. The talk describes a framework using Windows Workflow Foundation technologies. The proposed framework supports collaborative study across heterogeneous compute grids through scripted workflows in the Matlab environment.
∑ A Process Meta Model to Support Policy Based Management in Workflow System presented by Hao Xu. The paper described a Policy-based and process-based management. The process meta model allow flexibility at design time, adaptability at run-time, and support business rules across the enterprise.
a Formal Foundation for Aggregating Scientific Workflows
presented by Frank Terpstra. The talk describes a formal model to allow reasoning about the execution models of workflow systems.† The model is based on I/O Automata to prove the correctness of workflows involving multiple workflow engines and execution models
The talks presented at the workshop did cover various issues related to workflow and their usage in e-Science. Following is the list of topic addressed in the workshop:
Looking at the list of issues addressed in the presentations, it is clear that there are opportunities for collaboration among the research groups. The ideal workflow systems for e-Science should indeed have all the features developed in various systems presented in this workshop. The ideal workflow management system should allow abstract workflow composition, and automatically or semi-automatic generates concrete workflow. It should allow a validation of the composed workflow preferably semantic before the execution. At run time the ideal workflow system should be able to use grid enabled resources, allow the monitoring and when needed apply changes to the workflow without having to restart or stop the execution. It should also allow job farming and parameter sweep, the execution of complex workflow using various systems, support data provenance, and provide intuitive user and developer interfaces.
