MARTE Profile-based MDA approach for semantic NFP-aware Web services
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.Comment: 10 pages, 5 figure
