Generating a Contract Checker for an SLA Language

Overview SLAng is a language for expressing Service Level Agreements (SLAs) under development as part of the European project TAPAS. It is defined using a meta-model, an instance of the Meta-Object Facility (MOF) model, in which the relationship between the syntax of the language and its domain of application is explicitly represented, and the violation semantics of the language defined using Object Constraint Language (OCL) constraints. The concrete syntax of the language is the XML Meta-data Interchange (XMI) mapping of the syntactic part of the meta-model. This paper describes how the Java Metadata Interface (JMI) mapping can be applied to the meta-model of the language to generate interfaces and classes to create and query SLAs and relevant service monitoring data in memory.
