ABSTRACT In this work, we propose GXLA, a language for the specification of Service Level Agreement (SLA). GXLA represents the implementation of the Generalized Service Level Agreement (GSLA) information model we proposed in a previous work. GXLA supports multi-party service relationships through a role-based mechanism. It is intended to catch up the complex nature of service interactivity in the broader range of SLA modelling of all sorts of it business relationships. The GXLA language is based on XML; it is defined as an xml schema. GXLA can be used by both service providers and service customers in order to configure their respective systems. Each party can use its own independent SLA interpretation and deployment technique to enforce the role it has to play in the contract. Finally, we illustrate our proposition through a use case. KEY-WORDS: Service Level Agreement; Policy Based Management; SLA specification.
