Subject: Proposal to close Rel 97
*REL-97* Spec 3.1.1 feature Design Active *Title:* Group ID lifetime (remove after) *Description:* See original mail <http://www.oasis-open.org/archives/wsrm/200309/msg00105.html> If we retain sequenceNumber as optional, we need to clarify what the semantics of removeAfter are for a simple ack only case (i.e., sequenceNumber not present). Perhaps it would only pertain if duplicate elimination is requested (and then it would be the lifetime of memory for duplication elimination for that message). If we have the case of duplicateElimination with SequenceNumbers then the removeAfter attribute is the lifetime for the persistent state required for duplicate elimination for that group. For duplicate elimination and ordered delivery the text is probably ok as is. ------ It needs to be stated in the ws-reliability protocol for sequence behaviour that the same values for the three qos parameters (Guaranteed Delivery, Duplicate Elimination, and Ordered Delivery) must be sent for every message in the sequence. Once this is stated, there is no reason to treat the concept of group any different for one which is only used for Guaranteed delivery. If the sender wishes to provide termination criteria for the group in this case, there is no harm in having the sender apply these criteria in a consistent manner. Thus Issue 97 needs to be closed, after we add the protocol requirement for all message in a group specifying the same values for the three Reliable Messaging qos parameters in their header. -- ---------------------------------------------------- Tom Rutt email: tom@coastin.com; trutt@fsw.fujitsu.com Tel: +1 732 801 5744 Fax: +1 732 774 5133
