English abstract:
Abstract. Recently, the Software-as-a-Service (SaaS) model has been
increasingly supported, becoming a major part of the new emerging cloud
computing paradigms. Although SaaS exists in different forms, supporting
and providing SaaS developed based Web services has attracted a
large effort from industries and academics because this form of SaaS
allows software to be easily composed and integrated to offer new services
for customers. Even though various service composition techniques,
based on functional and non-functional parameters, have been proposed,
the issue of service contract compatibility has been neglected. This issue
is of paramount importance in the Web services-based SaaS model
because services are provided by different providers, associated with different
contracts which are defined by different specifications. This paper
proposes techniques for supporting service composers to deal with the
heterogeneity of service contracts in service composition. We describe a
novel approach for modeling and mapping different service contract specifications,
and a set of techniques for evaluating service contract compatibility.
Our techniques consider contract terms associated with data and
control flows, as well as composition patterns. Illustrating scenarios are
proposed to demonstrate the efficiency of our techniques.
