Group Abbreviation:
graap-wg
Group Name:
Grid Resource Allocation Agreement Protocol WG
Area:
Compute
Group Leadership:

| Philipp Wieder | philipp.wieder@udo.edu | Secretary |
| Wolfgang Ziegler | Wolfgang.Ziegler@scai.fraunhofer.de | Chair |
Group Summary:
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 been published May 2007 as an OGF Proposed Recommendation: Just recently an errata version has been published fixin a few typos in the non-normative part. The new version supercedes the version of 2007 (see
GFD.192). Along with this document the group has published the specification for extended negotiation and renegotiation on top of WS-Agreement as WS-Agreement Negotiation (see
GFD.193).
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, Grids and Clouds. In the context of OGF, the relation to the Open Grid Services Architecture (OGSA) is of special importance.
The group is now working on a RESTful implementation of WS-Agreement.
Community request: In case you have implemented WS-Agreement, we would appreciate if you could invest the time and fill in this
questionnaire. Also, if you plan to implement WS-Agreement Negotiation please let us know. Thank you.
Please find more information regarding the following topics on the respective pages of the
GRAAP Wiki:
*
Events related to WS-Agreement, GRAAP, and SLAs
* Existing
implementations using WS-Agreement
* A discussion on
interoperability between different WS-Agreement implementations
* A list of
publications related to WS-Agreement and SLAs
* A discussion on SLA
re-negotiation
Title: WS-Agreement Specification V1.0
Abstract: This document describes the Web Services Agreement specification which comprises an SLA template format and a Web Services protocol for establishing agreements between two parties such as consumer and provider of a service. Published as GFD.107.

Title: WS-Agreement Specification Version 1.0 Experience Document
Abstract: This document describes the implementation experiences of independent implementations of WS-Agreement along with an overview of the projects that have implemented WS-Agreement so far. It also presents the features of WS-Agreement used by 6 of the implementations. Finally, the document contains information on set-up and results of an experiment where two independent implementations of WS-Agreement were used to mutually exchange templates describing jobs.

Seven Questions:
1. Is the scope of the proposed group sufficiently focused?
2. Are the topics that the group plans to address clear and relevant for the Grid research, development, industrial, implementation, and/or application user community?
3. Will the formation of the group foster (consensus-based) work that would not be done otherwise?
4. Do the group's activities overlap inappropriately with those of another OGF group or to a group active in another organization such as IETF or W3C?
5. Are there sufficient interest and expertise in the group's topic, with at least several people willing to expend the effort that is likely to produce significant results over time?
6. Does a base of interested consumers (e.g., application developers, Grid system implementers, industry partners, end-users) appear to exist for the planned work?
7. Does the OGF have a reasonable role to play in the determination of the technology?
