Because Web services are autonomous and loosely coupled, BPEL processes are susceptible to a wide variety of faults. However, BPEL only provides limited constructs for handling faults, which makes fault handling a time-consuming and error-prone task. In this paper, we propose a declarative approach to enhancing the reliability of BPEL processes. Our solution specifies fault handling logic through a set of event- condition-action (ECA) rules which build on an extensible set of fault-tolerant patterns. These ECA rules are integrated with normal business logic before deployment to generate a fault-tolerant BPEL process. We also develop a GUI tool to assist designers to specify ECA rules. Experiments show our approach is feasible.","PeriodicalId":208234,"journal":{"name":"IEEE International Conference on Web Services (ICWS 2007)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129308591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is particularly true for processes that subject the composition of services advertising different information flow policies. To provide a systematic approach to manage the information flow between composed services, we present a methodology that derives cooperating distributed processes of a centralized specification with respect to their information flow policies. Our contribution shows how service compositions, that cannot be realized with centralized orchestrations or inconsistent choreographies, can be realized with equivalent decentralized executions in an inexpensive and in a reasonable manner.","PeriodicalId":208234,"journal":{"name":"IEEE International Conference on Web Services (ICWS 2007)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124713297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such contexts, it is crucial to grant access to the semantic model and its data only to the authorized users. In this paper, we present a fine-grained access control model specifically tailored to semantic models. One of the relevant features of the model is the granularity of the resources that can be protected. Access control can be enforced at the level of both the model's concepts and the concepts' instances by means of a query rewriting strategy. The proposed model has been implemented adopting the XACML standard and the SeRQL query language; services exposed by the implementation can be used to trans- paretly integrate authorization into existing systems.","PeriodicalId":208234,"journal":{"name":"IEEE International Conference on Web Services (ICWS 2007)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125910985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transactional support to integrated businesses via composing individual Web services is a critical issue. Current Web services protocols (e.g. BPEL4WS) have been proposed to deal with this issue on a strong assumption that each Web service is compensatable for a recovery purpose. It is arguable that Web services composition requires more transactional support beyond the compensation-based solution. This paper looks into the problem of transactional support for composing and scheduling those Web services that may have different transactional properties. The transactional properties of workflow constructs, which are fundamental to the composition of Web services, are thoroughly investigated. The concept of a connection point is introduced to derive the transactional properties of composite Web services. The scheduling issue of composite Web services is also discussed.","PeriodicalId":208234,"journal":{"name":"IEEE International Conference on Web Services (ICWS 2007)","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115775104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It provides a round robin algorithm for scheduling the workload of the Web services and keeps updating the availability of each Web service.

However, the complexity of the OWL-S grammar makes it difficult to construct an OWL-S ontology manually. This paper presents an efficient method for generating OWL-S ontologies from UML diagrams, which are widely used for software design and development. The proposed method uses a class diagram to represent a domain ontology and sequence or activity diagrams to represent the behavior of a business process. It also uses UML profiles to support various features of OWL-S. Finally, an XMI file extracted from UML diagrams is transformed into an OWL-S ontology via an XSLT script. Experimental results with a large volume of UML diagrams show that the proposed method deals with the control flow of complex processes and is superior to previous methods.","PeriodicalId":208234,"journal":{"name":"IEEE International Conference on Web Services (ICWS 2007)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130908182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
