Abstract

In this paper we describe a tool for a model-based approach to verifying compositions of web service implementations. The tool supports verification of properties created from design specifications and implementation models to confirm expected results from the viewpoints of both the designer and implementer. Scenarios are modeled in UML, in the form of Message Sequence Charts (MSCs), and then compiled into the Finite State Process (FSP) process algebra to concisely model the required behavior. BPEL4WS implementations are mechanically translated to FSP to allow an equivalence trace verification process to be performed. By providing early design verification and validation, the implementation, testing and deployment of web service compositions can be eased through the understanding of the behavior exhibited by the composition. The approach is implemented as a plug-in for the Eclipse development environment providing cooperating tools for specification, formal modeling, verification and validation of the composition process.

LTSA-WS:用于基于模型验证web服务组合和编排的工具

在本文中，我们描述了一个工具，用于基于模型的方法来验证web服务实现的组合。该工具支持对从设计规范和实现模型创建的属性进行验证，以从设计人员和实现者的角度确认预期的结果。场景在UML中以消息序列图(MSCs)的形式建模，然后编译成有限状态过程(FSP)过程代数，以简洁地建模所需的行为。BPEL4WS实现被机械地转换为FSP，以允许执行等效跟踪验证过程。通过提供早期的设计验证和确认，可以通过理解组合所表现的行为来简化web服务组合的实现、测试和部署。该方法作为Eclipse开发环境的插件实现，为组合过程的规范、形式化建模、验证和确认提供协作工具。
