Non-functional properties play an important role in all service related tasks, especially in discovery, selection and substitution of services. It is simple to imagine a scenario in which multiple services which provide the same functionality can fulfill a user request. In this case the ability of the user to differentiate between the services depends upon their non-functional properties. Modeling, managing and performing service related tasks such as discovery, composition, negotiation and agreement based on NFPs become fundamental challenges in Service-Oriented Architectures especially in real business settings. Directly connected to the tasks mentioned above are the specification, enforcement and management of Service Level Agreements (SLAs). SLAs give the service consumer some level of guarantee that the provider and the service/s that they provide will operate within acceptable bounds - particularly with regards to non-functional properties and QoS values. At the same time SLAs serve a role for the provider in planning resource allocation and avoiding unexpected legal wrangles. With the ever-growing demand for eBusiness, service providers are increasingly interested in enforcing contracts electronically allowing autonomous supervision of service status and management. Machine-understandable NFPs and QoS models are therefore key to the widespread uptake of SLAs as well as all of the service related tasks mentioned above.
This workshop aims to tackle the research problems around methods, concepts, models, languages and technology that enable management of non-functional properties and Service Level Agreements in the context of Service Oriented Computing. This workshop aims to bring together researchers and industry attendees addressing these issues, to promote and foster a greater understanding of how the management of NFP, QoS and SLAs can assist business to business and enterprise application integration.
