Excerpt from Appendix B of GFD-C.1: Where the OGF knows of rights, or claimed rights, the OGF secretariat shall attempt to obtain from the claimant of such rights, a written assurance that upon approval by the GFSG of the relevant OGF document(s), any party will be able to obtain the right to implement, use and distribute the technology or works when implementing, using or distributing technology based upon the specific specification(s) under openly specified, reasonable, non- discriminatory terms. The working group or research group proposing the use of the technology with respect to which the proprietary rights are claimed may assist the OGF secretariat in this effort. The results of this procedure shall not affect advancement of document, except that the GFSG may defer approval where a delay may facilitate the obtaining of such assurances. The results will, however, be recorded by the OGF Secretariat, and made available. The GFSG may also direct that a summary of the results be included in any GFD published containing the specification. OGF Intellectual Property Policies are adapted from the IETF Intellectual Property Policies that support the Internet Standards Process.

© 2006 Open Grid Forum 4 Agenda Result of last meeting and progress since then Defining the messages Role and handling of constraints
© 2006 Open Grid Forum 5 Re-negotiation sequence Re-negotiation is a sub-state of contracted Both parties obligated by the superseding agreement once the CreateAgreement has been accepted by the responding party New agreement supercedes previous one
© 2006 Open Grid Forum 6 Re-negotiation – Agreement states Starting point for re-negotiation is the Observed state where the contract is in force New agreement to supersede the previous: There is no Superceded state in WS-AG, thus use Terminated? In case of negotiation starting point is an empty Agreement
© 2006 Open Grid Forum Re-negotiation is a sub-state of Observed Both parties obligated by the superceding agreement New agreement supercedes previous one Re-negotiation – state machine
© 2006 Open Grid Forum Re-negotiation – messages RenegotiationRequest sent by the Modification Initiator RenegotiationReject sent by the Modification Responder RenegotiationAccept sent by the Modification Responder GetNegotiationTemplate sent by the Modification Initiator (in case the RenegotiationRequest was accepted, with the Negotiation context derived from current Agreement with additional Negotiation constraints) CreateQuote sent by the the Modification Initiator to the Modification Responder (carrying the initial non-binding quote) ModifiedQuote sent by either party (carrying the modified non-binding quote) CreateAgreement sent by the Modification Initiator RenegotiationNotPossible can be sent by either party indicating that the re-negotiation is not/no longer possible
© 2006 Open Grid Forum Next steps Create new Agreement factory interface inheriting from the old one + getQuote New Agreement State: Superceded Adding Superceded will result in a loss of backward compatibility. Two ways Use V1.1 for changes in the state definitions and base V2.0 on 1.1 (resource properties are completely changed) Add a only new resource property Oliver checks whether there is a smoth transition possible Raise the issue on the mailng list Need description how the Agreement can implement the Agreement factory port type Need description for specification of change of obligations (time) Need definition of negotiation constraints Need to assign writers
