MATINEE: A Quality-of-Service-aware Event Semantics Modeling Language

Distributed event-based systems have risen in significance over the last few years across many different application domains. Still, the configuration of available communication middleware solutions remains a tedious task driven by technical terms and manual performance optimization. We present the Metis Quality-ofservice-aware Semantics Modeling Language (MATINEE), a domain-specific language for modeling the Quality-ofService (QoS) requirements and semantic properties of event-based systems in the terminology of the application domain. No knowledge of the technical terms of the underlying middleware solution is required by the application developers to conduct the configuration. Embedded in a novel configuration methodology provided by the Massive Multiuser Event InfraStructure (Metis) project, MATINEE specifications are interpreted to automatically derive optimal middleware configurations without the need for manual optimization. The purpose of MATINEE is to provide a flexible language that can easily be adapted to different application domains. We focus on the language specification of MATINEE, briefly sketch our configuration methodology and present related language approaches.
