Towards Formal Verification of Web Service Composition
نویسندگان
چکیده
Correct notation for specifying the composite service alone is not sufficient to guarantee reliability, thus comes a strong demand on modeling and verifying web services composition languages. This paper presented a formal method of web service composition verification based on Petri net. Focus is given on BPEL4WS specification, of which both behavior semantics and communication semantics are covered. Meta-model transformation rules are given and automatic verification process is also introduced.

A model for specification, composition and verification of access control policies and its application to web services
Despite significant advances in the access control domain, requirements of new computational environments like web services still raise new challenges. Lack of appropriate method for specification of access control policies (ACPs), composition, verification and analysis of them have all made the access control in the composition of web services a complicated problem. In this paper, a new indepe...
متن کاملWeb Service Choreography Verification Using Z Formal Specification
Web Service Choreography Description Language (WS-CDL) describes and orchestrates the services interactions among multiple participants. WS-CDL verification is essential since the interactions would lead to mismatches. Existing works verify the messages ordering, the flow of messages, and the expected results from collaborations. In this paper, we present a Z specification of WS-CDL. Besides ve...

متن کاملTowards Formal Verification of Web Service Composition
Web services composition is an emerging paradigm for enabling application integration within and across organizational boundaries. Current Web services composition proposals, such as BPML, WSBPEL, WSCI, and OWL-S, provide solutions for describing the control and data flows in Web service composition. However, such proposals remain at the descriptive level, without providing any kind of mechanis...
متن کاملFormal Modeling and Verification for Web Service Composition
Web service composition is an important reuse way of service resources, through which large scale and complex applications based on Internet can get the newer and more reliable resources among the distributed nodes. An important challenge for web services composition is how to ensure the correctness and reliability of the composition process. CPN(Colored Petri Net)as a formal modeling and verif...
