STIL (“Strumenti Telematici per l’Interoperabilità delle reti di imprese: Logistica digitale integrata per l’Emilia-Romagna”, i.e.,telematic tools for inter-firm networks interoperbility: digital logistics for the Emilia-Romagna region). 

STIL defines an ICT infrastructure which offers mechanisms and policies for the semantic integration of applications (eServices) which realize strategical features for the value-chain. An eService is a software entity deployed by a service provider across the Internet. eServices can be statically selected by subscribing off-line contracts, or dynamically discovered using several approaches (for example, the SP2A approach). Obviously, an eService can be selected not only for its functionalities, but also for the quality of service (QoS) it guarantees.
