“…They demonstrate this ability by generating a WSDL meta-model from the WSDL XSD published by W3C and manually refining it to remove XSD or XML specific elements leaving behind only pure WSDL elements. They also propose a metamodel approach to support integration and interoperability between the different aspects and standards of web-service systems [13], based on UML-related research, where model transformations to allow for integration and interoperability are already established. First, they discuss the mechanisms from both UML and web services and compare them based on five criteria: containers, composite structures, messaging, links and mechanisms.…”

With the increasing adoption of the web-services stack of standards, service-oriented architecture has attracted substantial interest from the research community which has produced several languages and methods for describing and reasoning about services. These languages cover many concepts ranging from individual services and their code generation from specifications, service semantics, service compositions and networks, economics and business aspects around service ecosystems etc. However, this abundance of specification languages has also resulted in communication difficulties between stakeholders and hinders tasks such as service composition, discovery and maintenance. The presented work is a step towards the unification of the specifications and different aspects of service systems using Model-Driven Engineering. We propose a generic and abstract web service meta-model called WSMeta, which has the ability to describe both operation-centric web services (WS-*) and datacentric web services (REST) and can be used in tasks such as service evolution analysis and service systems maintenance.

International audienceThis paper presents a method for merging UML models which takes place in a quality evaluation framework for Web Services (WS). This framework, called iTac-QoS, is an extended UDDI server (a yellow pages system dedicated to WS), using model based testing to assess quality. WS vendors have to create UML model of their product and our framework extracts tests from it. Depending on the results of the test execution, a mark is given to WS. This mark gives to the cus- tomers an idea about the quality of WS they find on our UDDI server. Up today, our framework was limited to WS which did not use other WS. This was justified by the fact that it is impossible for vendors to cre- ate a good model of a foreign product. Our method for model merging solves this problem: each vendor produces models of its own product, and we automatically merge the different models. The resulting model from this merging represents the composition of the different WS. For each type of diagram present in the models (class, instance or state- chart diagram), a method is proposed in order to produce a unique model. In addition to this, a solution is proposed to merge all OCL code in the class modeling the WS under test. Unfortunately, this pro- cess introduces inconsistencies in the resulting model, that falsify the results of the subsequent test generation phase. We thus propose to detect such inconsistencies in order to distinguish inconsistent and un- reachable test targets

This paper presents a method for merging UML models which takes place in a quality evaluation framework for Web Services (WS). This framework, called iTac-QoS, is an extended UDDI server (a yellow pages system dedicated to WS), using model based testing to assess quality. WS vendors have to create UML model of their product and our framework extracts tests from it. Depending on the results of the test execution, a mark is given to WS. This mark permits to customers to have an idea about the quality of WS they find on our UDDI server. Up today, our framework was limited to WS which did not use other WS. This was justified by the fact that it is impossible for vendors to create a good model of a foreign product. Our method for model merging solves this problem: each vendor produces models of its own product, and we automatically merge the different models.

Unfortunately, this process introduces inconsistencies in the resulting model, that falsify the results of the subsequent test generation phase. We thus propose to detect such inconsistencies in order to distinguish inconsistent and unreachable test targets.
