The latest deliverables include the so-called \"Basic Security Profile\" and the \"Reliable SecureProfile\". This gives rise to the question whether or not Web Services adopters can rely on interoperability of Web Services stacks, in particular in terms of security and reliability features. To answer this question, we thoroughly analyze two important Web Services stacks for interoperability of WS-Security and WS-Reliable Messaging features. Our analysis shows that security and reliability features are far from being implemented in an interoperable manner. Additionally, we reveal that some of those interoperability problems are not even covered by WS-I profiles and therefore conclude that WS-I's work has not yet resulted in Web Services interoperability.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"319 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116423459","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}

New services emerge while old ones become obsolete and need to be replaced. In such settings, composite services need to be adaptive to changes in user requirements and the environment. This paper proposes a conceptual framework for modeling compositional adaptation for services founded on a requirements monitoring facility. This facility helps maintain adherence between user requirements changes and the dynamics of service composition structure and quality attributes. Specifically, user requirements are represented as goals and soft goals, service composition structure is represented with a CSP-like grammar, and the adaptation mechanism is based on AI planning. The proposed approach is evaluated in a service simulation environment of real-world supply-chain adaptation scenarios.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122963486","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}

The main component, the process model, describes the interaction protocol between a Web service and its clients. Such protocol includes not only the inputs, outputs, preconditions and results of the service, but also the control flow and data flow within the service. In this paper, we propose an approach to verify various properties of the process model of an OWL-S service. We define a set of mapping rules to translate a process model into a process algebra model and use a dedicated model checker to check the properties of the translated model. We handle not only the control flow of the process model, but also the binding-based data flow. Pre-conditions and results are also included in our approach. As a case study, we use a reasonably complex online book shopping Web service.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130821115","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 feature has not been worth its costs in realistic Web service usage scenarios until now. However, its absence may pose restrictions and impede possible benefits in a future scenario, where mediators are both willing and able to effectively minimize the amount of wirelessly transmitted data in the Internet of Services. This paper describes how developments in the Internet of Services start to motivate the automatic enablement of safe (i.e., always up-to-date) client-side caching for Web services. It presents our solution for generically adding this feature to any Web service, and, based on new experiments, reveals the limits beyond which the approach can offer significant benefits.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"229 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123316515","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}

The monad-based model can help us formally describe and further study on software components and services through monads' properties such as abstraction, reflection and composability. This model relatively improves service reuse and discovery, and it significantly facilitates web service composition and enables integration of legacy applications.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133431127","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}

A layered model of viewing DPSs is proposed consisting of the data acquisition, syntactic and semantic layers. It is shown that by defining all three layers, a DPS may be generated and managed exclusively by its declarative definition. This will increase the agility and efficiency with which DPSs may be deployed and managed. As a development model, a set of reusable messages are created, these messages are to be semantically annotated using a view over the domain ontology and are syntactically represented such that they may be exported to XML Schema. These messages are used within the DPS definition where their views over the domain ontology are parametrized and the data acquisition layer is defined to acquire data from the source.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132556286","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}

As more web services can be used over the Internet, the need to find efficient algorithms for web services composition that can deal with large amounts of services becomes important. These algorithms must deal with different issues like performance, semantics or user restrictions. In this paper we present an A* algorithm which solves the problem of semantic input-output message structure matching for web service composition. Given are quest, a service dependency graph with a subset of the original services from an external repository is dynamically generated. Then, the A*search algorithm is used to find a minimal composition that satisfies the user request. Moreover, in order to improve the performance, a set of dynamic optimization techniques has been implemented over the search process. A full experimental validation with eight different public repositories has been done showing a good performance as in all tests as the algorithm finds a valid solution with minimal number of services and execution path.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134609206","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}
