Links provided on request.  These documents have an immense amount of analysis and assets, all described in excellent detail.
* Meeting agenda
* Gap analysis

Here are my meeting notes.  Additions and improvements welcome.

Determining expected capabilities for X3Dv4.1
a. “Gap Analysis” seems premature since many APIs are still undergoing development.
b. Perhaps “Expected Features” or some other name is more appropriate.
c. Goal result remains: list of capabilities for inclusion in X3Dv4.1 Component or Profile.

Three active areas of work provide all information that we need. Different perspectives helpful.
a. WebXR releasing initial draft for devices, some things well defined and others deferred.
b. OpenXR is defining APIs for interoperability among hardware interfaces.
c. ISO Mixed Augmented Reality (MAR) Reference Model defining common requirements.

“X3D AR Demos” as goal for Web3D/SIGGRAPH 2019 Conferences is an excellent strategy.
a. Anybody can implement X3D + AR however they like, opportunity to influence everyone.
b. Art of the possible - extending X3D with capabilities of existing toolkits and HTML also.
c. Greatness is welcome. 8)  No permission or approvals from this working group is needed!

Regarding ISO MAR work
a. Baseline goal is abstract reference model describing mixed AR/VR in jargon-neutral way.
b. Numerous slidesets in recent Korea Chapter meeting describe much progress.
c. Draft ISO specification documents are sharable with Web3D Consortium members.
d. Gerry Kim of Korea University is group lead and willing to brief this group, example times are Wednesdays at 4 or 5 pm pacific (7 or 8 eastern), which is Thursday morning Korea.
