MARTE Profile-based MDA approach for semantic NFP-aware Web services
This addresses the problem of efficient selection and composition of Web services for developers and users by enabling semantic NFP descriptions, though it appears incremental as it builds on existing standards like W3C WS-Policy and MARTE.
The paper tackles the challenge of describing and integrating semantic Non-Functional Properties (NFPs) in Web services, which are complex and lack standardized specifications, by proposing a Model-Driven Architecture (MDA) approach using MARTE profiles to automatically generate enriched services with policies.
Non Functional Properties (NFPs) such as security, quality of service and business related properties enhance the service description and provide necessary information about the fitness of its behaviour. These properties have become crucial criteria for efficient selection and composition of Web services. However, they belong to different domains, are complex, change frequently and have to be semantically described. The W3C standard WSPolicy,recommended to describe these properties doesn t define standardized specifications that cover all NFPs domains. Moreover, it doesn t provide an easy manner to express them independently of domains, and doesn t support their semantic. This paper proposes a Model driven approach to describe and automatically generate enriched Web services including semantic NFPs. It explores both the use of the OMG Profile for Modelling and Analysis of Real-Time Embedded Systems (MARTE) and the W3C standards. Mapping rules, from NFPs profile to WS-Policy and SAWSDL files, transforms NFPs into policies associated with WSDL elements.
