2. Calendar and Meeting Review

a. Vince reported on ISO SC4 TC184 6-day meeting in Chicago.  Also present were Christophe Mouton and Anita Havele.  Details to follow on CAD and BoD mailing list.  Web3D presentations will be posted publicly.  Meeting page online at

3. Specification Updates

a. Specification Status Tracking (from last week)

* 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/

We discussed whether it made sense to further merge these.  Primary goal is to keep track of progress.  These documents seem like simplest way for Consortium to track.

Suggestion: add annotated links at bottom to relevant process pages.

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

b. Dick and Don are close 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 in our notes.

Curious correction we applied:  ComponentInfo had a legacy method "function String getProviderName()" that, to our knowledge, has never been implemented or utilized.  Our recollection is that this is from the earliest days of X3D v3.0 development where the concept was that software providers might be able to share software components.  That hasn't happened of course, mostly because software components typically don't work that way.

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

c. Humanoid Animation (H-Anim)

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

Meanwhile in our attempts to fully implement

- some of the site/segment/joint names are inconsistent across LOAs
- LOA 0, 1, 2, 3, 4 are not fully structurally consistent, they vary with respect to Site locations.

Joe noted that ISO 7250 has been updated several time since we last took a hard look.

Further implementation/evaluation work is definitely needed.  Of interest is that Joe, Don and William have been working on a comprehensive table that lists Joints, Segments and Sites together on an LOA-by-LOA basis.  This is helping us identify inconsistencies and will later help build testing tools for validation of each LOA.  Draft table found online at

https://github.com/x3d/HAnim (probably will get renamed as HumanoidAnimation)
https://github.com/x3d/HAnim/blob/master/HAnimHierarchyWeb3d-19774-V2.0.txt

Planned trajectory:
- continue review and implementation
- finish implementation work for Architecture and Motion Animation
- finish HAnim spec revisions by 15 JAN 2019
- review in mid January at Korea Chapter
- submit to ISO ~15 FEB 2019 as requested

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

c. John Carlson and Don continue working on Java, JavaScript and Python language bindings.  We meet most weeks, see Web3D Calendar.

After some discussion we created the following draft public pages:

* 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

Goal for next week: have the attached words transcribed to match website page structure for a new Working Group.  References:

	Web3D Working Groups

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

5. Review recent and upcoming CY2018 work.

Looks like we have a full plate!  Additional items for November-December are welcome.

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

6. Next week:

- Invited speaker for next week Thursday's CAD Design Printing Scanning Working Group
   Bob Lipman, Research Engineer NIST
   https://www.nist.gov/people/robert-r-lipman
   Among many other people, a long-time VRML X3D contributor.

- Continue on all items.  Wow we are busy!

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

We finished a huge amount of discussion and work in 95 minutes.  Again wow.  Thanks everyone.

all the best, Don
