In this paper we propose a meta-model for non- functional property descriptions targeted to support the se- lection of Web Services. The approach is based on the ex- plicit distinction between NFP offered by providers and re- quested by users, on the concept of policy that aggregates NFP descriptions into single entities with an applicability condition, and finally on a set of constraint operators, which is particularly relevant for NFP requests. The semantic meta-model embracing the above perspective is defined by a BNF syntax whose semantics is formalized by an ontology. The ontology has been formalized in OWL-DL and WSML to provide for logical syntaxes. The logic upon which the meta-model supports NFP-based selection is discussed in the paper.

Abstract
In this paper we propose a meta-model for non- functional property descriptions targeted to support the se- lection of Web Services. The approach is based on the ex- plicit distinction between NFP offered by providers and re- quested by users, on the concept of policy that aggregates NFP descriptions into single entities with an applicability condition, and finally on a set of constraint operators, which is particularly relevant for NFP requests. The semantic meta-model embracing the above perspective is defined by a BNF syntax whose semantics is formalized by an ontology. The ontology has been formalized in OWL-DL and WSML to provide for logical syntaxes. The logic upon which the meta-model supports NFP-based selection is discussed in the paper.
