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. Papers should be written in English and must not exceed 12 pages, strictly following Springer LNCS style (http://www.springer.de/comp/lncs/authors.html) including all text, references, appendices, and figures.

Example for extending the agreement state for ws agreement negotiation
by Oliver Wäldrich 26 Sep '08

26 Sep '08

I just attached an example, how an extesion for an agreement state in WS-Agreement-Negotiation could look like: <wsag:AgreementState xmlns:wsag="http://schemas.ggf.org/graap/2007/03/ws-agreement"> <wsag:State>Terminated</wsag:State> <wsag-neg:NegotiationState xmlns:wsag-neg="http://schemas.ggf.org/graap/2008/10/ws-agreement-negotiat ion"> <wsag-neg:SubState>Superseeded</wsag-neg:SubState> </wsag-neg:NegotiationState> </wsag:AgreementState> We could also allow some additional element here, that points to the new created agreement.

Extension of agreement states for WS-Agreement-Negotiation
by Oliver Wäldrich 26 Sep '08

26 Sep '08

Dear all, After the discussion in the GRAAP group concerning the extension of the AgreementState port type for the negotiation protocol, it turned out that this is not necessary. It is still possible to define substates for the states defined in the WS-Agreement recommendation. The important structures for this are listed below: <xs:simpleType name="AgreementStateDefinition"> <xs:restriction base="xs:string"> <xs:enumeration value="Pending"/> <xs:enumeration value="PendingAndTerminating"/> <xs:enumeration value="Observed"/> <xs:enumeration value="ObservedAndTerminating"/> <xs:enumeration value="Rejected"/> <xs:enumeration value="Complete"/> <xs:enumeration value="Terminated"/> </xs:restriction> </xs:simpleType> AgreementStateDefinition defines the WS-Agreement states as an enumeration. <xs:complexType name="AgreementStateType"> <xs:complexContent> <xs:extension base="wsag:InnerAgreementStateType"> <xs:sequence> <xs:element name="State" type="wsag:AgreementStateDefinition"/> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="InnerAgreementStateType"> <xs:sequence> <xs:any minOccurs="0" namespace="##other" processContents="lax"/> </xs:sequence> </xs:complexType> The AgreementStateType defines one element State that can take a value defined in AgreementStateDefinition. AgreementStateType also extends InnerAgreementStateType, which allows extending AgreementStateType with an abritary XML document. Therefore, it is possible to add a document in the WS-Agreement-Negotiation namespace, which defines e.g. a substate for an AgreementState. How these extensions (e.g. substates) are defined, is then part of the WS-Agreement-Negotiation specification. However, this approach would be a fully compliant and compatible way to introduce substates in WS-Agreement-Negotiation with respect to the base WS-Agreement specification.

SLA examples
by Omer F. Rana 16 Sep '08

16 Sep '08

Dear Colleagues, I was wondering if you have examples of: 1. Service Level Agreements (SLAs) that you have come across. These do not need to be in WS-Agreement format -- any format would be fine. 2. If you have SLAs that have arisen from your own research/development projects that you are willing to share. 3. If you have SLAs that are encoded in WS-Agreement or some other commonly used specification. I would like to create a repository of these, and will be making this generally accessible. Would be grateful for pointers/examples.A personal email to o.f.rana(a)cs.cardiff.ac.uk would be great. regards Omer -- http://www.cs.cf.ac.uk/User/O.F.Rana/index.html / work-fax:+44(0)29-2087-4598 work:+44(0)29-2087-5542 / other:+44(0)7956-299981 / distributed collaborative computing / room n2.14 / school of computer science / cardiff university queen's buildings / newport road / cardiff cf24 3aa / wales / uk

Sessions at OGF24
by Wolfgang Ziegler 14 Jul '08

14 Jul '08

Dear GRAAPians, as discussed during OGF23 some of us plan to attend OGF24 and we intend to organise one or more sessions focussing on the experience document and the negotiation protocol. Since I expect the session request procedure soon I'd like to know who is planning to attend OGF24. Moreover, if you plan to participate I would be interested in your opinion on how many GRAAP sessions we should have there. My first guess would be at least two: one for the advancement of the experience document and the second one for the negotiation protocol. But I am open for having three as we had in the past.

***SPAM*** WS Agreement Negotiation Framework
by Sebastian Hudert 17 Apr '08

17 Apr '08

Dear GRAAP Working Group, my name is Sebastian Hudert and I am affiliated with the Department of Information Systems Management at the University of Bayreuth. I have been working on a negotiation framework for WS-Agreement together with Dr. Heiko Ludwig (IBM Research) and Prof. Guido Wirtz (University of Bamberg). After meeting Wolfgang Ziegler at the CoreGRID Integration Workshop he suggested to introduce our ideas to the GRAAP WG in order to contribute to the WSAgreementNegotiation standard. Our main idea was to create a framework with which not only one particular negotiation protocol (e. g. an English Auction) can be executed, but one that allows for a variety of different negotiation protocols to be used according to the particular situation the system is in. We proposed an XML-based language that can be used to define a negotiation protocol in a machine-processable manner. A protocol description, coded as an XML document, therefore represents all the input needed by a service requestor or provider in order to take part in the particular negotiation process. Using the derived data structure we propose a two-staged negotiation process: 1. Exchange process: During this phase a negotiation protocol description document is created (possibly based on pre-defined protocol types and referring to a given WS-Agreement Template) and distributed to the future negotiators within the system. This process is implemented as a set of simple interfaces and valid method invocation sequences in analogy to the WS-Agreement standard itself. 2. Negotiation process: After supplying all negotiators with the protocol description these nodes engage in the actual negotiation process. We propose a set of generic interfaces able to cope with all negotiation protocols that can be described with the description language we defined. This way the logical steps from an initial need for a resource or the will to sell one to reaching a valid WS-Agreement are: Protocol Definition (XML-based Documents) à Exchange of protocol description to future negotiators (Exchange process) à Negotiation (Negotiation process) à Agreement formation I included a Paper presented at KIVS 07 on this topic. We hope that you find our ideas an interesting input for the ongoing standardization effort. I will attend the OGF 23 in Barcelona which would also be a possibility for me to present our work in the working group session, if there is interest among the WG.
