telecon on 3/28
by Jim Pruyne 29 Mar '07

29 Mar '07

All, We're scheduled for our next telecon on March 28. The US has changed to daylight savings time, and we agreed last time to shift one hour earlier outside the US, so we go back to the original times in the US, and other areas should be one hour earlier. My best calculation is that he times are as follows, but the US central time is the benchmark to convert from should I be incorrect: 9:00AM Central Standard Time US (GMT-0500) which should be: 10:00AM Eastern Standard Time US 1600 Germany 2300 Japan The current dialin numbers are: Toll number: 8324452343 Toll free number: 8664809967 Conference code: 8578310 Please see Wolfgang's recent message for the current status of the document, and last steps prior to submitting to the editor. Best, --- Jim

Issues in the final draft
by Tianchao Li 28 Mar '07

28 Mar '07

Hello, here is a list of the issues that I discovered in the final draft. Best regards, Tianchao Li 1. IMPORTANT (Agreement.wsdl) The following part should be removed from Agreement.wsdl <xs:element ref="wsag:AgreementServiceReference" minOccurs="0" maxOccurs="unbounded" /> and the following be removed from agreement_types.xsd <xs:element name="AgreementServiceReference" type="wsag:AgreementServiceReferenceType" /> <xs:complexType name="AgreementServiceReferenceType"> <xs:sequence> <xs:any namespace="##other" processContents="lax" /> </xs:sequence> <xs:attribute name="ServiceName" type="xs:NCName" /> </xs:complexType> AgreementServiceReference was already identified to be duplicate and should be removed. (Comment#14 of last year) 2. IMPORTANT The definition and usage of faults is different for AgreementFactory and PendingAgreementFactory. It seems that the PendingAgreementFactory has not been updated to catch up with the fault definition changes in AgreementFactory. 3. MINOR (Agreement.wsdl and AgreementFactory.wsdl) Unnecessary soap namespace definition for soap and wsa in WSDL xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" (no reference to soap) xmlns:wsa="http://www.w3.org/2005/08/addressing" (all reference are in type definition, it is enough to define it in the schema element) 4. MINOR (agreement_types.xsd) Several element definition use separate closing element tag. This is inconsistent with the style of other element definitions. These include the following: -current- <xs:element name="ServiceTermReference" type="xs:string"> </xs:element> <xs:element name="KPITarget" type="wsag:KPITargetType"> </xs:element> <xs:element name="CustomServiceLevel" type="xs:anyType"> </xs:element> <xs:element name="CustomServiceLevel" type="xs:anyType"> </xs:element> -suggested- <xs:element name="ServiceTermReference" type="xs:string" /> <xs:element name="KPITarget" type="wsag:KPITargetType" /> <xs:element name="CustomServiceLevel" type="xs:anyType" /> <xs:element name="CustomServiceLevel" type="xs:anyType" />

Are attached. Note that the final draft of WS-Agreement can be found at: http://forge.gridforum.org/sf/docman/do/downloadDocument/projects.graap-wg/… We will meet again in two weeks. The time will be one hour earlier, back to 9:00 AM central time US with the corresponding changes around the world. --- Jim Notes from Mar. 14 Teleconference --------------------------------- Attendees --------- Jim Pruyne Toshi Nakata Wolfgang Ziegler Agenda Items ------------ - Karl sent suggestions on re-structuring the pseduo-schema some. Wolfgang and Oliver suggest that we follow this suggestion. - We changed all references to GGF to OGF. - We added some acknowledgements based on contributions to this last draft. - We removed unneeded references. - Three sessions have been requested for OGF20. One on WS-Agreement, two more to discuss negotiation including presentations from others who are starting on this topic.

telecon on 3/14
by Jim Pruyne 14 Mar '07

14 Mar '07

All, We're scheduled for our next telecon on March 14. The US has changed to daylight savings time, but for this first meeting I will strive to keep the times the same in other countries. Therefore, the times in the US will be one hour later, and I hope that means that the time will be the usual outside the US. The times are as follows: 10:00AM Central Standard Time US (GMT-0500) which should be: 11:00AM Eastern Standard Time US 1600 Germany(?) 0000 Japan ALSO, the dial-in numbers have seemingly changed again. You should now use: Toll number: 8324452343 Toll free number: 8664809967 Conference code: 8578310 And, finally, after all of the confusion, the good news. I believe I have the final draft of WS-Agreement. It can be found at: http://forge.gridforum.org/sf/docman/do/downloadDocument/projects.graap-wg/… (sorry for the long URL). If we have no complaints during this telecon, I'll submit it right afterward. Best, --- Jim

First call for papers: Usage of Service Level Agreements in Grids Workshop
by Wolfgang Ziegler 09 Mar '07

09 Mar '07

******************************************************************* We apologize if you received multiple copies of this posting. Please feel free to distribute it to those who might be interested. ******************************************************************* -------------------------------------------------------------------------------- Call for Papers Usage of Service Level Agreements in Grids Workshop Austin, Texas, USA, September 19, 2007 http://www.coregrid.net/sla-workshop2007/ to be held in conjunction with The 8th IEEE International Conference on Grid Computing (Grid 2007) Austin, Texas, USA, September 19 – 21, 2007 -------------------------------------------------------------------------------- DESCRIPTION As the Grid evolves to become an infrastructure for providing and consuming services in research and commercial environments, mechanisms are needed to agree on the objectives and the quality of such service provision. This could be facilitated by means of electronic contracts between service consumers and one or more service providers, in order to achieve the necessary reliability and commitment on both sides. Such contracts help to establish a well-defined relationship between a service provider and a client in the context of a particular service provision. This is especially important if the services or resources to be used come from different administrative domains, or if commercial service provision needs to be supported. Service Level Agreements (SLAs) are a promising approach to establishing these kinds of guarantees and relationships. This workshop will provide a forum to present current research and up-to-date solutions from research and business communities. TOPICS OF INTEREST Topics of interest for the Usage of Service Level Agreement in Grids workshop include but are not limited to: * Areas benefiting from SLAs * Languages to express SLAs (e.g. SLOs, BLOs, QoS, Guarantees, Penalties) * Protocols to conclude and negotiate SLAs * Technologies for management and observation of SLAs * Static vs. Dynamic SLAs * Business models & Grid economy * Validation techniques for SLA parameters * Comparison and matchmaking of SLA and policy descriptions * Managing user expectations via SLAs * Multi-party SLAs and SLA chaining * SLA-based resource discovery, co-scheduling and resource reservation * Registry Services and repositories for SLA * SLA-based trust management including VOs PROCEEDINGS Accepted papers will be published in the CoreGRID Springer Series. For more information regarding paper format and style please visit the author's instruction link at http://www.coregrid.net/mambo/content/view/360/332. PAPER SUBMISSIONS Authors are invited to submit manuscripts reporting original unpublished research and recent developments on the topics of interest. Submitted papers should be formatted according to the CoreGRID Springer style format (please see http://www.coregrid.net/mambo/content/view/360/332) and should not exceed 10 pages including figures and references. Papers should be submitted electronically in PDF format by sending it as an e-mail attachment to sla-workshop2007(a)fz-juelich.de. All papers will be peer reviewed and the comments will be provided to the authors.
