  A lot of works has been especially interested to the functional aspect of Web
services. Nevertheless, it is necessary to describe their non-functional
properties such as the security characteristics and the quality of service. The
WS-Policy standard was recommended in 2007 to describe Web services policies
including the non-functional properties. However, it doesn't provide any
information of their meaning necessary for automatic processes. In this paper,
we propose a Model Driven Architecture approach founded on W3C standards to
generate WSDL language based files including semantic policies. We use a
package of WSDL and WS-Policy profiles and transformations rules to generate
Web services interfaces files including policies. We extend a XML schema
profile according to SAWSDL standard to define semantic non-functional
properties domains. This work contributes to minimize the development cost of
Web services including semantic policies. Moreover, the generated services can
be automatically processed in discovery, selection and negotiation tasks.
