SECO2: Service Contract Compatibility
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. The SECO2 proposes techniques for supporting
service composers to deal with the heterogeneity of service
contracts in service composition. These techniques support (i)
modeling and mapping different service contract specifications, (ii)
the evaluation of service contract compatibility, (iii) the recommendation for
service contracts associated with service composition, (iv) user-specified service
contract-based composition.
