Standardization - OGF


Grid Resource Allocation Agreement Protocol Working Group


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. Currently, the group focuses on WS-Agreement interoperability and usage scenarios. This group works on standards.


List of partners active in this research group:

Oliver Wäldrich Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V. Contributing Member
Wolfgang Ziegler Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V. Co-chair

There is one approved OGF document in this group: Web Services Agreement Specification (WS-Agreement).

State of the work

WS-Agreement is a proposed recommendation. The work on WS-Agreement-Negotiation is under way, a first draft was presented in the beginning of 2009. Besides the negotiation of Agreements the group has also started to define the re-negotiation of previously established agreements.

The group works in parallel on the experience document for WS-Agreement. This document contains a list of current implementations of WS-Agreement, a table with the features of WS-Agreements available in the different implementations, the description of an interoperability experiment between two implementations (one of them being based on the framework developed in PHOSPHORUS) and several profiles for WS-Agreement.
