Subject: Issue verification 2.52, 2.33, 2.51
I will be out of the office next week, June 12-18, so here are my issue verification items. WSN2.52: TopicExpressionDialects to be singular Line 334 of version 1f of WS-BaseNotification specification uses the term TopicExpresssionDialects. Instead use the singular term. TopicExpressionDialect. Update the schema and change the cardinality of this element to minOccurs=0 (instead of minOccurs=1). I've attached revisions of wsnb-draft-01i.doc and b1.xsd to correct the cardinality for this element so that you can have zero or more dialect elements. *** 2.33Message ordering/interleavingSusan Malaika, John Fuller WSN2.33: Message ordering/interleavingWhat is the guarantee that the NP submits events for delivery in the same order in which they were generated? Should we provide a way of flagging how interleaving of event streams can be handled? Should two subscriptions for the same topics be guaranteed to see the same interleaving of messages?Specifications?~@? WS-BaseNotificationProposed RecommendationAdd some text to the BaseN to explicitly point out that the possible issues with message ordering/interleaving are not addressed by BaseN. WSN Policy document may address this issue.NotesThe issue was initially raised by David Hull via email - http://www.oasis-open.org/apps/org/workgroup/wsn/email/archives/200501/msg00015.html During Jan/Feb 2005 F2F, this issue was discussed. The resolution is summarized in the Proposed Recommendation section above. Status: Open ? approach agreed Date: Jan 31, 2005Agreed Approach: See Proposed RecommendationContact: David HullCross Reference: I've added the following text to the NonGoals section of ...-draft-0i1.doc (also included are my changes for 2.52)... "Defining message ordering or interleaving policies for delivery is beyond the scope of WS-BaseNotification." *** 2.51Flexible placing of metadataMartin Chapman, John FullerWSN2.51: Flexible placing the notification metadataCurrently there is no provision for raw messages to carry the notification metadata (SubscriptionReference, Topic, etc). The only option for carrying notification metadata is to use Notify message which has well defined schema elements for carrying the metadata. Alternative bindings for notification metadata should be allowed, for example, in the case of raw messages, the metadata may appear as SOAP Headers.Specifications?~@? WS-BaseNotificationProposed Recommendations Define the notification metadata in a stand alone manner and allow its inclusion in different ways by the actual messages.In particular:- Define the notification metadata (subscriptionReference, topic etc.) components before describing the Notify message, and update the Notify description to reference the metadata descriptions- Update the raw message description to make a non-normative statement that the notification metadata elements may appear in raw messages, for example as SOAP headers NotesMay 05 F2F: This issue was raised and an approach was agreed.Status: Open ? approach agreedDate: May 20, 2005Agreed Approach: See proposed recommendation.Contact: Martin Chapman Cross Reference: It looks like this is ready to close. The latest schema has the metadata broken out as elements and in the base notification draft there is text in the section about notification metadata indicating the elements may be used as components in raw messages.
