ACTION: Drummond Reed to include a first draft of the "Current State Mapping" appendix in the next Working Draft. ACTION: Drummond Reed to update Darrell O'Donnell's proposed diagram per the feedback in the 2022-08-11 TATF meetings and then figure out where it best belongs in the next draft. ACTION: Neil Thomson to create a first draft of a proposed three-dimensional "cube" diagram that can serve as an anchor to tie the different views of the stack. ACTION: Drummond Reed to incorporate Neil's diagram into the next Working Draft. ACTION: Jo Spencer to move a copy of his slide deck of 3 diagrams to the ToIP Google Drive for the TATF.
	ToIP Technology Architecture Specification Review Topics		Discussion of progress on the working draft of the ToIP Technology Architecture Specification: TAS NEW WORKING DRAFT 03 Google doc version <== USE THIS VERSION STARTING AUGUST 17 for any comments to sections 1 thru 6. TAS OLD WORKING DRAFT 02 Google Doc version <== DO NOT USE THIS VERSION (except temporarily Aug 18-20 to make comments in sections 7 onwards) Evolution of the ToIP Stack <== NEW proposed companion document ToIP Protocol Stack Diagrams (Google Slides) <== All of all our past diagrams (some of which have been copied to TAS Source Diagrams) TAS Source Diagrams (Google Slides) <== SOURCE DIAGRAMS used in the TAS TATF Google Drive Folder <== WHERE ALL OF THE ABOVE may be found TAS GitHub Markdown version TAS GitHub issues list
10 mins	NEW Google doc version of the spec (Working Draft 03)	Drummond Reed	After our discovery last week that the Google doc we had been using for Working Drafts was not in the ToIP Google Drive, Drummond created a new Google doc that we will begin using now starting with Working Draft 03. However, Drummond was not able to consolidate all comments and suggestions on Working Draft 02 into Working Draft 03. So the instructions for the next few days only are: If you have any comments or suggestions on sections 1 thru 6, please make them to the new Google doc (Working Draft 03). <== THIS IS THE GOOGLE DOC WE WILL BE USING UNTIL WE FINISH. If you have any further comments or suggestions on the rest of the sections, make them quickly to the old Google doc (Working Draft 02). Drummond will notify the `#tswg-tech-arch-tf` channel on Slack as soon as he has consolidated the rest of the sections from Working Draft 02 into Working Draft 03. <== AT THAT POINT WE WILL STOP USING WORKING DRAFT 02. ACTION: Drummond Reed to complete consolidating the rest of the sections of Working Draft 02 into Working Draft 03. ACTION: Drummond Reed to post to the `#tswg-tech-arch-tf` channel on Slack as soon as he has consolidated the rest of the sections from Working Draft 02 into Working Draft 03.
5 mins	NEW Evolution of the ToIP Stack document	Drummond Reed	In considering where and how to deal with the "Current State Mapping" diagram and explanation, the conclusion was that we should publish a companion living document that explains the whole process the ToIP Foundation is following in the development of the ToIP stack. See screenshot #1 (below). This resulted in small changes to sections 1 and 4. The concept now is to describe the purpose of this document (and a "hook" for reading it) in Appendix B. ACTION: Drummond Reed to do his best to have a draft of this new Evolution of the ToIP Stack document ready for the ToIP Steering Committee meeting on Wednesday August 24.
5 mins	Section 6.1: Design Goals	Drummond Reed	See the revised list of four (previously three) relationship properties. Integrity has been added.
5 mins	Section 6.2: The Four Layer Pattern	Drummond Reed	Darrell O'Donnell's diagram replaced the table we had used previously to illustrate the types of functions at various layers. See screenshot #2 (below). Antti Kettunen said that with his "fresh eyes" looking at this section, it could use some additional explanation. ACTION: Antti Kettunen to propose some additional revisions to section 6.2.
5 mins	Section 6.3: High Level System Architecture	Drummond Reed Jo Spencer	Jo Spencer's diagram has been added. See screenshot #3 (below). Also, a fourth type of interaction has been added (at sumapnair's suggestion): Intermediary System to Intermediary System. In the NA/EU meeting there was consensus that was not needed, so it was removed. APAC: We discussed some of the comments that have been added to this section in Working Draft 03, plus Jo's thoughts on the revisions to his diagram (screenshot #3). ACTION: Jo Spencer to propose additional revisions to section 6.3.
10 mins	Section 7.1: Requirements numbering & linking	Drummond Reed	Appendix A now includes a table of requirements that is simply a placeholder at present—only the very first requirement is synced with the spec (to show how it should work). ACTION: Drummond Reed to finish updating and cross-linking the requirements table in Appendix A once Working Draft 03 is complete.
5 mins	Plan for the coming week		ACTION: Neil Thomson to complete preparation of the Use Cases table to place into section 5 to complete Working Draft 03 by next week's meeting. ACTION: ALL to review sections 1-6 in Working Draft 03 and make any comments or suggestions.
5 mins	Review decisions/action items Planning for next meeting	Chairs
