	[x3d] X3D WG Minute 5 Oct 2018

Can we copy (or excerpt) these minutes for the x3d-public mailing list?


1. Any further followups on Khronos Texture Format (KTF)?


2. X3DUOM update.  Have updated diagram for X3D Unified Object Model (X3DUOM) Creation process.  Have also converted the autogenerated X3DUOM .xml into a .json version (using Altova XMLSpy).  Both versions seem useful.

3. New working group proposal.  Leslie Sikos and Don Brutzman have been working on a charter outline for an X3D Semantic Web working group.
- enable Semantic Web inference and reasoning to easily use X3D as presentation layer
- applying a range of standards by W3C and Linked Open Data communities
- support multiple Web3D working group domains of interest: CAD, printing and scanning, medical usage, cultural and natural heritage, possibly geospatial and Humanoid Animation, potentially Building Information Models (BIM).

Draft points are being circulated for discussion.  If approved by this will be a members-only Working Group whose products will get public visibility for best effect.  Detailed version expected for review next week.

Attendance at an important conference this week is yielding a lot of excellent insight.

	International Semantic Web Conference (ISWC) 2018

"The International Semantic Web Conference (ISWC) is the premier international forum for the Semantic Web Community. ISWC 2018 in Monterey, CA (USA) will bring together researchers, practitioners and industry specialists to discuss, advance, and shape the future of semantic technologies."

(Of tangential note: https security is considered a minimum requirement in all presentations concerning trust and security.)


4. ProtoInstance, ProtoDeclare, ExternProtoDeclare typing.

Work on X3DJSAIL continues to minimize need for authors to include containerField information (i.e. special parent-child node relationships).  Progress includes the library ability to determine ProtoInstance node type if a ProtoDeclare is present in the scene (by inspecting the first node present there).  Since X3DJSAIL is produced directly from X3DUOM, that reflects overall design of X3D quite thoroughly.

	X3DJSAIL: X3D Java Scene Access Interface Library

	X3D Scene Authoring Hints: containerField

Of note is that when an author defines a new node in ExternProtoDeclare, this appears to be the only case in X3D where direct validation of strong typing in the scene graph is not possible.  Correctness can only be checked when the external prototype is loaded.

We are considering a recommendation that ExternProtoDeclare information include node type as part of X3Dv4.  This has the potential to improve X3D Quality Assurance (QA) even further.  Initial discussion welcome.

5. X3D Specification Timeline: continued progress.  Are we able to fill in dates/deadlines/status on this tracking tool?

5.3	Track B, simultaneous submission of NWIP and CD:

5.4	The Track A and Track B spreadsheets are an attempt to reformat the existing work of
