Specifying Services using the Service Oriented Architecture Modeling Language (SoaML) - A Baseline for Specification of Cloud-based Services

The Service oriented architecture Modeling Language (SoaML) is a new specification from the Object Management Group (OMG) that provides support for modelling services. The SoaML specification defines three different approaches to specifying services; simple interfaces, service interfaces and service contracts. In this paper we provide an overview of the SoaML language constructs and discuss the three different ways to specify services. Furthermore, we provide practical modelling guidelines for how the different SoaML service specification approaches can be aligned and used as a baseline for specifying cloud-based services.
