Don,
I don’t know if I also mentioned my conversions from JSON to Java
failed…used setValue instead of setMetadata. I have some free time this
evening and will work on JSON schema validation, fieldTypes.js, and
mapToMethod.js as generated from X3DUOM and found in X3DJSONLD. These JS
files impact my serializers (exported Java) and schema validation of
JINLOA4.json. Likely I will be able to do a build, and then do spot
checking for any issues.
I did not understand the difference between Humanoid in the abstract spec
and HAnimHumanoid in the concrete spec.
Excellent analysis, Don, and Merry Xmas to you and yours.
