OGF 25 session outcome
by Wolfgang Ziegler 11 Mar '09

11 Mar '09

Dear GRAAPians we had two productive sessions at OGF 25 in Catania last week. The slides of the two sessions have been uploaded to the gridforge space of GRAAP along with the minutes and a presentation of "A lightweight annotation approach of WS-Agreement based specifications" which was given by Ioannis Kotsiopoulos. We continued the work on the experience document, the next draft version taking into account the recommendations and requests of the GFSG will be available soon. We also continued the discussion of the negotiation. Based on the outcome of OGF 24 a first prototype implementation was presented. Since a number of the participants will meet again in Dagstuhl in two weeks for a seminar on SLAs we decided to have two half day work group meetings there to finalise the experience document and the initial document on negotiation. I attach the minutes of the two sessions to this mail for your convenience.

Otherwise fall back to the people specified below: - Akogrimo (Bastian Koller) -> fill questionnaire - BREIN (Bastian) - BEinGRID BEs (Igor) - JSS - SmartLM (Oliver & Wolfgang) - Section about generic WS-Agreement frameworks -> coordinated by Dominic -> write for each framework: - dependencies (middleware stack, specifications) - ... - Wolfgang will pass list of items to Dominic & Oliver for completion and generation of questionnaire - forward questionnaire to - WSAG4J -> Oliver - BREIN framework -> Bastian - NegMgr -> Dominic - see below - Section about interoperation Testing -> Dominic & Oliver -> coordinated by Oliver - Comments from Projects taken from survey -> Dominic - Suggestion for new section: add analysis, which parts are used by implementations and which parts are not used -> Igor - Further procedure: first we generate a beta version of the document, then circulate to everybody who gave input (for updates/changes) - input from GFSG regarding interoperability demonstration: - Need true interoperability of two independent code bases -> Both use same template - Issue: Hosting environments incompatible - adapters are ok to circumvent incompatibilities of hosting environments -> demonstration will be job submission with best effort jobs - we will include an interoperable template in experience document, afterwards we will write a new document discussing various use cases and interoperability - Discussion on "WS-Agreement Frameworks" section in experience document - have created list of criteria -> Wolfgang sends this to Oliver & Dominic for another iteration - possible answers to several questions will be: "automatically handled by framework", "can be implemented in domain specific implementation", "not supported" - Should we found a new group for Negotiation? -> no, just add an extension since Negotiation is based on WS-Agreement 1.0 and only requires small changes resulting in WS-Agreement 1.1 - update Charta to include Negotiation (Wolfgang) - GFSG expressed desire to specify term languages (eg. for Advance Reservation) - Some topics shall be addressed at SLA Workshop in Dagstuhl: - 1/2 day on Microspec for advanced reservation as JSDL Extension (WSDL files), will be passed to JSDL working groups - 1/2 day on negotiation (definition of WSDL files) - Presentation by Ioannis Kotsiopoulos, UoM - SLA terms/metrics/... for domains are NOT specified in WS-Agreement -> Proposal of semantic annotation - semantic annotation = reference to ontology - provides semantic interoperability - no need to change WS-Agreement - Annotation by SAWSDL, is backwards compatible - tools: SASLA4j library - Comments: very interesting, might fit well into metrics of WS-Agreement GRAAP Session #2: Negotiation ------------------------------------- - Implementation for Negotiation exists for SmartLM based on WSAG4J framework - started with negotiation - will be extended to re-negotiation - see slides for details - legal issues need to be discussed (how long is old agreement valid in case of renegotiation) - discussion: - during iterations of negotiation the creation constraints remain the same - is the document passed during the negotiation and the template really the same? -> seems ok - should negotiate be allowed to return >1 template at a time? - yes, simpler for a client to handle this - should negotiate accept >1 template as parameter? - no, user can send several requests sequentially. Advantage: easier for the agreement responder to find out what the agreement initiator wants. -> requests to change: - NegotiateOutputType: - minOccurs="0" - maxOccurs="unbound" - superseding state missing - will be added -> Oliver + Wolfgang - How do we address PendingAgreementFactories? - First ignore this, then ask for input on first version of WSDL files from GRAAP mailing list and work on PendingAgreementFactory in parallel - Do we need an exception for the provider to tell that it is not willing to renegotiate any further? -> No, WS-Agreement has too limited exception features, needs a general overhaul there as well -> it could be put in the final agreement ("this is the last offered agreement") - Usecases for validation of (re-)negotiation: - Graceful termination - Service Responder wants to make changes - Service Initiator wants to make changes - Broker Scenario (broker collects offers) - quote is accepted/rejected / no quote generated - maybe more in wiki - is an extension of agreement context needed? - tracking quotes? - superseding of agreements - maybe, Oliver creates proposal -> proposal of document ready by SLA workshop in Dagstuhl (Oliver & Wolfgang) GRAAP Session #3: ----------------- cancelled

WS-Agreement Veriosn 1.0 experience document
by Philipp Wieder 04 Mar '09

04 Mar '09

Dear All, please find the first draft of the WS-Agreement experiment document at GridForge [1] (thanks Dominic for starting and pushing, thanks Wolfgang for your input, thanks all projects for implementing and feedback). We got some last minute additions from the BEinGRID project (thanks Igor), which also can be found at GridForge [2]. Wolfgang will discuss the document tomorrow at the session(s) and we will try to publish it asap, which, I guess, is not only in the group's interest. Best regards, Philipp. [1] http://forge.gridforum.org/sf/go/doc15550?nav=1 [2] http://forge.gridforum.org/sf/docman/do/listDocuments/projects.graap-wg/doc…

OGF: SLA framework
by Igor Rosenberg 02 Mar '09

02 Mar '09

Hello GRAAP group, Within the EU BeinGrid project (beingrid.eu), we've been developing an SLA framework for GT4. It is based on a component architecture (by this, understand independent modules). I have some material that describes it that I could pass to the community, including a paper (attached). Implementation of the different components is finished (nearly all components are licensed as Apache V2, only one is freeware binary), and we're currently making sure it all integrates smoothly. I think it should be advertised to the OGF community (at least the guys and girls interested in GT4). I also propose that from the work done, we could try to standardize the SLA frameworks that exist for Grids (GRIA, GRASP, Unicore, and now GT4); btw our framework is based on the March 2007 WS-Agreement specification of the OGF, which describes SLA contracts (www.ogf.org/documents/GFD.107.pdf) but is meant to be generic (different SLA formats can be plugged in) . What would be the way forward? Who should I get in touch with?

Service Description Terms
by bao.leduc＠orange-ftgroup.com 18 Oct '08

18 Oct '08

Dear, I'm a new comer of WS-Agreement. I have a stupid question about Service Description Terms (SDT). What is the semantic of logical compositor (wsag:all, wsag:oneormore, and wsag:exactlyone) when it is used to describes service terms. Why we use a logical operator mixing with service description? Thank you, Le Duc Bao Phd student at Orange Labs, France

CfP: International Workshop on Intelligent Service Management (ISM'09), March 24th, 2009, Leipzig, Germany
by André Ludwig 15 Oct '08

15 Oct '08

[ our apologies should you receive this message more than one time ] CALL FOR PAPERS --------------------------------------------------------------------- The International Workshop on Intelligent Service Management (ISM'09) https://sabreconference.wifa.uni-leipzig.de/frontend/index.php?folder_id=207 March 24th, 2009, Leipzig, Germany --------------------------------------------------------------------- collocated with SOFTWARE, AGENTS, AND SERVICES FOR BUSINESS, RESEARCH, AND E-SCIENCES (SABRE 2009), http://www.sabre-conference.com. Mission ------- Service-oriented computing has emerged as the most promising design paradigm for distributed information systems. The vision of service-oriented computing is to capture business relevant functionalities of existing software systems as services and use service composition to form composite applications. While this vision has yet to be achieved in practise, in particular the application of intelligent systems and techniques promises significant advancements for an adaptive and reliable construction and management of service-oriented applications and systems. The purpose of the workshop is to present and discuss recent significant developments at the intersections of service-oriented computing and intelligent systems and technologies, and to promote cross-fertilization of ideas and techniques between these fields. In particular, the workshop focuses on techniques from multi-agent systems and artificial intelligence research for an automated construction and management of service-oriented applications/composite services. This includes critical challenges such as agent-based service composition management, self-managed service compositions, intelligent management of service quality concerns, adaptive and reliable evolution and optimization of services. Topics ------ ISM'09 encourages a multidisciplinary perspective and welcomes papers that address intelligent management of service-oriented applications and systems in general or in the context of specific domains. Workshop topics of interest include, but are not limited to the following: * Intelligent techniques for determining quality requirements for SOA-based systems * Intelligent deployment, monitoring, control and exception-handling for service execution and delivery * Agent-based negotiation and management of service quality aspects * Intelligent Service Level Agreement lifecycle management mechanisms (development, negotiation, deployment, monitoring, compliance evaluation, termination) * Agent-enabled adaptation, evolution, and optimization of services and processes * Intelligent management frameworks and platforms for service-oriented computing * Agent-based service composition, orchestration, and choreography * Self-managed service compositions and processes that exhibit intelligent adaptive and autonomic properties * Integration and management of agent-based services and service-oriented agents * Resource models for intelligent management of specific QoS requirements * Intelligent management of the QoS mapping between business processes and the underlying SOA-based systems * Autonomic and intelligent QoS management in SOA-based systems * Applications and case studies of intelligent service management Key dates --------- * Submission Deadline: 05 December 2008 * Notification of Acceptance: 05 January 2009 * Camera-ready Submission: 15 January 2009 * Workshop: 24 March 2009 Submission and publication -------------------------- Authors are invited to submit original, previously unpublished research papers.
