| Abstract |
|
SLAng is an XML language for defining service level
agreements, the part of a contract between the client and
provider of an Internet service that describes the quality attributes
that the service is required to possess. We define
the semantics of SLAng precisely by modelling the syntax of
the language in UML, then relating the language model to
a model that describes the structure and behaviour of services.
The presence of SLAng elements imposes behavioural
constraints on service elements, and the precise definition
of these constraints using OCL constitutes the semantic description
of the language. We use the semantics to define a
notion of SLA compatibility, and an extension to UML that
enables the modelling of service situations as a precursor
to analysis, implementation and provisioning activities.
