Agenda: ongoing review of progress and issues list for X3Dv4.
Dick and I then continued our review with Michalis on draft specification for X3D PBR.
==================================
The X3D Graphics Working Group addresses all X3D specification issues and coordinates the technical development of future improvements.
http://www.web3d.org/working-groups/x3d
Members and invited experts are welcome. We are an open organization. Please let us know if you have an important topic to present or discuss.
Each week we report out both public and member-only information - membership has value. To become a Web3D Consortium member:

[5] Mantis Issue Tracker (requires 2 sets of member login)
https://www.web3d.org/member-only/mantis/view_all_bug_page.php
You can quickly see all X3Dv4 issues (with tag V4.0) by selecting the filter "X3Dv4" within mantis.
As specified in the reference pages, our next steps of implement/evaluate over the next quarter include
- finished specification prose in github,
- addressing all mantis issues,
- proper example X3D models available for each node/field,
- validation tools confirming examples are satisfactory,
- two or more implementations (X3DOM and X_ITE, others),
- consensus by working group, approval by Web3D Consortium, submission to ISO.
Here are refined milestones from X3Dv4 Implementations Status page:
_Milestones Timeline_
* /26-31 July 2019/. Publish draft specification plus examples and implementation updates at Web3D2019/SIGGRAPH 2019 conferences.
* /16 December 2019/. Working group accepts X3Dv4 new-technology submissions, with rich capability set publicized for implementation work.
* /31 January 2020/. Specification Editors provide ISO Working Draft on github for use and confirmation by Web3D Consortium members.
* /First quarter 2020/. Implement new components in X3D players, evaluate scene examples for conformance. Publish weekly progress updates.
* /When completed/. Completed ISO Working Draft submitted to X3D Community, Web3D Consortium members, Web3D Board of Directors.
* /BoD approval/. Working Draft upgraded to Committee Draft and submitted with NWIP to ISO.
* /Sequential updates/. Specification updates for 19775-2 Scene Access Interface (SAI), file encodings (XML, ClassicVRML, JSON etc.) and language bindings (JavaScript, Java, Python), and X3D Semantic Web (possibly 19775-3).
==================================
2. *IPR statements* - still pending, Anita is communicating with each individual involved.
Status?
Terms of membership and a requirement for contributing technology is to sign the Web3D Intellectual Property Rights (IPR) Policy asserting that no known patented technology subject to licensing is being submitted.
https://www.web3d.org/sites/default/files/page/Join%20the%20Web3D%20Consortium/Web3D_IPR.pdf
Web3D Executive Director Anita Havele has checked past records. Since many of these were signed years ago, we simply plan to ask everyone contributing to X3Dv4 specification to again assert that they are following the IPR policy.
==================================
3. *Web3DUX Working Group Proposal*
Status?
Thanks for all review of Web3DUX Working Group Proposal and draft Charter. Dr. Feng Liu and Dr. Amela Sadagic have submitted to Web3D Board of Directors, feedback from Board of Directors review is expected soon.

==================================
5. *Mantis Issues*
We have 78 issues tagged as X3Dv4.0. Current issues list attached last week.
https://www.web3d.org/member-only/mantis/view_all_bug_page.php
Our primary work today is reviewing the list and planning whether other focus topics are needed this month.
* Mantis Definitions
http://www.web3d.org/member/mantis-definitions
* Mantis Workflows
http://www.web3d.org/member/mantis-workflow
Priority: issues that affect schemas, validation and examples.
Next up:
a. Mantis 1271: add hidden field to Shape
https://www.web3d.org/member-only/mantis/view.php?id=1271
b. Status for unassigned tasks (will filter and display on screen)
c. Next issues to pursue... request participants identify one issue and be prepared to address it each week.
==================================
6. *Teleconference Information*
We are using the Web3D Consortium Zoom channel, to good effect. It allows use of internet audio, screen sharing and chat with links.
We meet regularly on Fridays 0800-0930 pacific. To join the teleconference:

==================================
Participants will review the public minutes to confirm that no member-only information is present.
Lots of effort continues. Thanks to everyone contributing, your work is important to all of us.
Everyone else, please consider how you are helping... there are things TODO for everyone.
We will schedule several small items and one more significant Mantis issue each week, repeating until done.
Have fun with X3D!
all the best, Don
