Abstract: To deal with the issue that Web services composition design specifications lack of formal semantics and formal verification methods,the paper outlines a top-down framework-iFrame4WS for Web services composition design and verification.In iFrame4WS,the process of Web services composition is divided into description level,abstract level and execution level.The formal model and verification approach are defined in abstract level so as to ensure the correctness of Web services composition.

Key words: Web services, Web services composition, formal model

摘要: 针对Web服务组合设计规范缺乏形式化的语义和验证方法的问题,提出了一个自顶向下的Web服务设计和验证的框架-iFrame4WS。在iFrame4WS中,将Web服务组合的设计方案划分为描述层、抽象层和执行层,并通过抽象层的形式化模型和形式化验证来检查Web服务组合的正确性。
