=========================
1. Prior meeting minutes:

	X3D Working Group meeting 9 NOV 2018: specifications review, X3D Semantic Web Working Group
	http://web3d.org/pipermail/x3d-public_web3d.org/2018-November/thread.html

=========================
2. X3D Semantic Web Working Group

Discuss and continue improving the draft pages.  Can we have charter and related pages ready for Web3D Board of Directors review at the end of the month?

* X3D Semantic Web Working Group
    http://www.web3d.org/x3d-semantic-web-working-group

* X3D Semantic Web Working Group Charter
    http://www.web3d.org/x3d-semantic-web-working-group-charter

* X3D Semantic Web Wiki
    http://www.web3d.org/member/wiki/x3d-semantic-web-wiki

=========================
3. Primary working group goal is X3D version 4.

	X3D Version 4.0 Development
	http://www.web3d.org/wiki/index.php/X3D_version_4.0_Development

New.  Can we propose certain parts of X3Dv4 as recommended for implementation testing by the end of the year?

Candidates:

a. 3D Printing and Scanning Profile.  Addition of Point size, Point normals, possibly point sprites.  Anything else?

b. Inline support for glTF.

c. Others?

For CAD Design Printing Scanning group's arena, there is a lot of work going on with STEP.  It would be could to consider our best strategies for STEP support in 2019: encourage translators/import/export?  Best practices?  Native support in X3D?

This is a year-end opportunity to prioritize the most feasible and valuable next steps for progress.  Discussion TBD.

=========================
4. Specification Updates

a. Specification Status Tracking

* X3D Graphics Standards: Specification Relationships
   http://www.web3d.org/specifications/X3dSpecificationRelationships.png

* Web3D ISO Current Specifications Timeline
   https://docs.google.com/spreadsheets/d/1GdVcjQIid0Hohc_ajmepVOESy2sLtHSVvbvsFni89w8

and following a separate timeline, intending both Committee Draft and submit simultaneously with New Work Item Proposal (NWIP)

* Web3D ISO Future Specifications Timeline
    https://docs.google.com/spreadsheets/d/15KoIa-tD2dTnqIbh3A1OqL_BMc3SpyiaVNTRPhSgTX0

=========================
b. Ecmascript SAI

Dick and Don continue working to finishing 19777-1 v3.3 Draft International Specification (DIS) X3D ECMAScript Scene Access Interface (SAI).  We serve as ISO editors for Standards Committee SC24 in this regard.  Changes are visible to Web3D members at

	X3D/ISO-IEC 19777/ISO-IEC 19777-1/ISO-IEC 19777-1 V3.3/ISO-IEC 19777-1 V3.3 DIS Prep/
	https://github.com/Web3DConsortium/X3D/tree/master/ISO-IEC%2019777/ISO-IEC%2019777-1/ISO-IEC%2019777-1%20V3.3/ISO-IEC%2019777-1%20V3.3%20DIS%20Prep

We are finding that everything is in fairly close agreement with 19775 Abstract Scene Access Interface (SAI), noted some small potential changes to SAI in our notes.

About to finish Clause 6.  Will have this ready for review in 1-2 weeks, members are welcome to review it now.

=============================
c. Humanoid Animation (H-Anim)

Monthly meeting minutes posted Wednesday night.

Mail from ISO to editors and SC24 stated that DIS text for v2.0 specifications of v1 Architecture and v2 Motion Animation was accepted.  A number of purely editorial comments were received.  They can be found on github.

https://github.com/Web3DConsortium/H-Anim/tree/master/ISO-IEC%2019774/ISO-IEC%2019774-1/ISO-IEC%2019774-1%20V2.0/ISO-IEC%2019774-1%20V2.0%20DIS%20Prep/Working%20documents
and
https://github.com/Web3DConsortium/H-Anim/tree/master/ISO-IEC%2019774/ISO-IEC%2019774-2/ISO-IEC%2019774-2%20V2.0/ISO-IEC%2019774-2%20V2.0%20DIS%20Prep/Working%20Documents

We are looking at ISO 7250 for correlation of body positions.

Renamed the github public archive for clarity, distinguishing from above member-only archive.

	https://github.com/x3d/HumanoidAnimation

Continuing progress by Joe Williams, William Glascoe and yours truly on cross-checking Joint-Segment names and hierarchy across all 5 Levels of Articulation (LOAs) [0..4].  A few naming mismatches were found and will be resolved to ensure that the validatable skeleton is consistent at all levels.  Joe has begun work on adding the corresponding listing of Site nodes and their position offsets.

=========================
d. Python.

Am trying to catch up to John Carlson and show his Pyjnius work running on my machine.  Next steps include examining candidate X3D Python SAI syntax and starting pages similar to the effort that successfully produced a working X3D JSON encoding.  Weekly teleconferences on Web3D line.

=========================
5. Quotation mark escaping issues in XML encoding and all corresponding X3D representations.

If time permits, quick review to figure out path to full resolution.

See recent email thread, we will also try to list all relevant Mantis issues.

=========================

Other issues?

Calendar review.

Have fun with X3D!

all the best, Don
