The goal of the GRAAP Working Group is to produce a set of specifications and supporting documents which describe methods and means to establish Service Level Agreements between different entities in a distributed environment. The WS-Agreement Specification V1.0, a Web Services protocol to establish agreements between two services, has recently (May 2007) been published as an OGF Proposed Recommendation (see GFD.107). Currently, the groups focuses on WS-Agreement interoperability and usage scenarios.

Within the scope of the GRAAP-WG are the definition, the negotiation, and the management of Service Level Agreements (SLAs). The group especially focuses on the usage of SLAs and WS-Agreement, an SLA format and protocol specified by the GRAAP-WG, in distributed systems and Grids. In the context of OGF, the relation to the Open Grid Services Architecture (OGSA) is of special importance.

The focus of GRAAP is currently on the interoperability testing of different WS-Agreement implementations (to evaluate the specification and to evolve from an OGF Proposed Recommendation to an OGF Recommendation) and on use cases. In addition, the group discusses the definition of a re-negotiation protocol to be used in the context of WS-Agreement.
