[Brutzman, Donald (Don) (CIV)]

Prior minutes

	X3D meeting minutes 22 FEB 2019: X3D v4 Development status categories
	http://web3d.org/pipermail/x3d-public_web3d.org/2019-March/010188.html

Topics planned from last week:

i. Agenda review

ii. Update of X3Dv4 Development page forthcoming, following restoration of capability.
    http://www.web3d.org/wiki/index.php/X3D_version_4.0_Development
    (snapshot attached for future comparison that changes will be correct)

iii. X3D design and events, review and discussion of documents/diagrams.

iv. Updated README of github specification pages attached for review.

Plus

v. Report on MetadataSet implementation efforts: as it turns out, the recently identified option to change default containerField value won't work, because all must match to ensure consistent parent-child relationship defaults.  Thus merging of MetadataSet.value and MetadataSet.metadata fields as a single MFNode Metadata.children field appears to be the only available resolution of this difficulty.  Looking ahead: since prior objections are theoretically reasonable but have never been observed in practice, request that examples demonstrating the necessity current paired-field approach be developed.  That way we can more directly evaluate this design issue.

	[x3d-public] X3D meeting minutes 3 FEB 2019: X3Dv4 mantis github specification changes, glTF plans, MetadataSet
	http://web3d.org/pipermail/x3d-public_web3d.org/2019-February/010048.html
	section 6. MetadataSet and /metadata/ fields.

Plenty to review today, ensuring that our progress continues to be clearly recorded and communicated.

all the best, Don
