In this framework, the users start with an abstract, and possibly incomplete functional specification of a desired goal service. This specification is used to compose a choreographer that allows communication between the client and the set of available component services, and is functionally equivalent to the goal service. However, if such a composition cannot be realized, the proposed approach identifies the cause(s) for the failure of composition. This information can be used by the user to minimally reformulate the goal to reduce the `gap' between the desired functionality. The process can be iterated until a feasible composition is realized or the user decides to abort. The approach ensures that (i) a choreographer, if one is produced by our composition algorithm, in fact realizes the user-specified goal functionality; and (ii) the algorithm is guaranteed to find a composition that meets the user needs as captured in the goal specifications (whenever such a composition exists)","PeriodicalId":365520,"journal":{"name":"2006 European Conference on Web Services (ECOWS'06)","volume":"290 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114202610","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}

Individual Web services are expressions over WSDL-defined operations while composed Web services are expressions over PEWS-defined services. This paper distinguishes two dimensions of PEWS. The control dimension describes the control workflow of the service, i.e. the order in which the operations of the Web service will be executed. No data constraints are imposed. The data dimension adds information flow to the control dimension. In order to analyse the composability and the substitutability of composed services, we introduce a trace-theoretical presentation of the language constructs.

We introduce AMPol (adaptive messaging policy), a service-oriented architecture that facilitates policy-aware, end-to-end adaptive messaging between multiple parties. AMPol provides services for expressing non-functional QoS policies, finding them, and carrying out system extensions to adapt to them. We implement this approach with a Web service middleware that allows parties to use policies for features like attachments, payment, encryption, and signatures. Our implementation demonstrates how AMPol can enhance the function of email messaging by enabling automatic deployment and use of features like cycle exhaustion puzzles, reverse Turing tests and identity based encryption without the need for global deployment or changes to the baseline messaging system","PeriodicalId":365520,"journal":{"name":"2006 European Conference on Web Services (ECOWS'06)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121738708","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 is desirable that SOAP, being the Web service transport protocol for interconnecting applications across organizations, performs efficiently in environments where there are a large number of transactions. This paper presents a novel approach to address this issue and hence improve Web services performance. We propose a similarity-based SOAP multicast protocol (SMP) that reduces the network load by optimizing the generated traffic size. In particular, SMP reuses the common template among the SOAP messages and only sends one copy of the common part to multiple clients. The results obtained from our experiments indicate that SMP achieved a 75 percent reduction in network traffic compared to traditional SOAP unicast","PeriodicalId":365520,"journal":{"name":"2006 European Conference on Web Services (ECOWS'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128984715","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}

Next-generation telecommunication networks, on the contrary, are characterised by the need to handle asynchronous interactions among distributed service components, e.g., to deal with long-running computations and with events produced by the network resources. As these worlds are more and more converging into a single application context, several solutions have been proposed to deal with asynchronous events in the context of Web services. In this paper we formalise and verify one such approach, viz., an original asynchronous extension of SOAP, and draw some conclusions. The formal model is specified as a set of communicating state machines. The semantics of the model is seen as a doubly-labelled transition system, and its behavioural properties are expressed in the action-and state-based temporal logic mu-UCTL and verified with the on-the-fly model checker UMC","PeriodicalId":365520,"journal":{"name":"2006 European Conference on Web Services (ECOWS'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131693544","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}

From a business perspective, the e-services must support the primary values that an organization strives for. From an operational perspective, the e-services must be devised such that they support the day-to-day activities in the business. In this paper, we report on an effort to use value models and \"service process models\" as the foundation for analysis and design of e-services. Value models facilitate the exploration of new e-services, whereas service process models relate e-services to specific activities in an organization's business processes. We elicited a set of principles and models for analysis and design of e-services, and we discussed the experiences of practicing the principles in a project from the health sector.

Interactions between services take place via messages in an asynchronous environment where communication and processing delays can be unpredictable; further, interacting parties are not required to be on-line at the same time. Despite loose coupling, many service interactions have timing and validation constraints. For example, business interactions that take place using RosettaNet partner interface processes (PIPs) such as request price and availability, request purchase order, notify of invoice, etc. have to meet several timing and message validation constraints. A failure to deliver a valid message within its time constraint could cause mutually conflicting views of an interaction. For example, one party can regard it as timely whilst the other party regards it as untimely, leading to application level inconsistencies. The paper describes how business interactions, such as PIPs can be wrapped by simple handshake synchronisation protocols to provide bilateral consistency, thereby simplifying the task of coordinating peer-to-peer business processes","PeriodicalId":365520,"journal":{"name":"2006 European Conference on Web Services (ECOWS'06)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124427202","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 principle, this generality enables a wide variety of domains to be covered. Yet, agreement terms need to be developed for each domain, to allow specific requirements to be expressed. When addressing a domain, one can either invent new agreement terms, or leverage on existing approaches. This paper proposes to extend the WS-agreement framework to address multimedia content negotiation. This work relies on an existing protocol for multimedia negotiation, widely used in networking and telecommunications, named session description protocol. This protocol is used as a framework to cover a variety of media (audio, video, images...). Besides building on a well-proven technology, our approach naturally allows the interfacing between the Web services realm and the networking-telecommunications realm, creating a host of new usage opportunities.

Generally, the selection process involves decision making in terms of non-functional properties of Web services such as QoS requirements. Since the number of Web services is rapidly increasing and the QoS of the Web services environment changes dynamically, the fast selection is important. This paper presents a fast method for quality driven composite Web services selection based on a workflow partition strategy. The proposed method partitions an abstract workflow into two sub-workflows to decrease the number of candidate services that should be considered. A mixed integer linear programming is utilized for solving the service selection problem. Experimental results show that the partition strategy performed faster than the optimal strategy.
