Using services across domain boundaries, be they organizations or self-managing components of large distributed systs, requires the setup of an agreent between the parties involved, defining the terms of the service including interfaces, security and Quality of Service (QoS) properties. In an on-dand environment in which services are contracted on a short notice, the establishment of an agreent as well as the setup of agreement-fulfilling and monitoring systs of the parties involved must be spontaneous and, partially, automated. WS-Agreent is a standardization effort being conducted in the Global Grid Forum defining a simple agreent establishment protocol, an XML-representation of agreements and agreent tplates as well as a runtime agreement monitoring interface, based on the WSRF set of standards.
