ABSTRACT
With the emerging of SOA, Web Services are used frequently to build software applications in a loosely coupled manner. A Web Service is the wide popular implementation of SOA. It is a software component allowing to expose services via Internet. It insures interactions between heterogeneous applications and systems and is platform independent. With the increasing growth in popularity of Web Services, discovering relevant Web Services becomes a significant challenge. Nevertheless, existing Web Services offer the same result regardless the user profile. Therefore, we are interested in defining an adaptable Web Service architecture. In a previous work we have proposed an UML extension named AWS-UML that describes the different allowed users profiles at the metamodel level according to the MDA principles and standards. As we modified the modeling process of the Web Service and so the resulting implementation code, we need also to extend the service description in order to support the additional adaptation informations. Thus, we introduce in the current paper an extension of the standard WSDL used to describe the service offered functionalities. Our proposal is named AWS-WSDL.

Adaptable Web Service Registry for Publishing Profile Annotation Description
UIC-ATC '13: Proceedings of the 2013 IEEE 10th International Conference on Ubiquitous Intelligence & Computing and 2013 IEEE 10th International Conference on Autonomic & Trusted ComputingWeb services are described via an XML-based language called Web Service Description Language (WSDL). They are then discovered through registries and repositories built upon a standard called Universal Description, Discovery and Integration (UDDI). Due ...
Adaptable web service registry for publishing context aware service composition
iiWAS '15: Proceedings of the 17th International Conference on Information Integration and Web-based Applications & ServicesIn this paper, we introduce a new registry that provides publishing adaptable composition Web services (CAC-WSR).
