Hi all, As you saw, I uploaded an updated draft of the Request/Reply document to the OASIS site. The changes in this version are that I added the description of a solution option to provide a request/reply service for MQTT 3.1.1 which satisfies the requirements specified in the document. Due to customer engagements, I am unable to attend the call this Thursday, but rather than wait another 2 weeks, David Horton (also from Solace) has agreed to present the solution to the group to start the education and feedback/comment process. What we’d like to present from the document is: - Overview of the proposed request/reply solution - Discussion of issues related to MQTT3.1.1 which make adding this or any metadata extension to the PUBLISH (and perhaps other) packets very difficult. Richard – could we please allocate some time for this discussion? Thank you, Shawn
