The error was in the source .x3d file, the MetadataSet within HAnimHumanoid need correct containerField definition:
* <MetadataSet name='HAnimHumanoid.info' containerField='metadata' etc.
all the best, Don

I think there's still a error in X3dToJson.xslt, conversion from XML to JSON produces

I believe this affects all my downstream serialzers.
I will double check that I am using the stylesheet.

Hi John, thanks for this elaboration of the question. Here is an in-depth explanation giving multiple related references that answer the question: yes, the /metadata/ field is part of HAnimHumanoid node.
More precise URL for HAnimHumanoid in HAnim v2.0 specification is
1. Part 1: Humanoid animation (HAnim) architecture, Clause 6 Object Interfaces, 6.2 Humanoid
2. https://www.web3d.org/documents/specifications/19774-1/V2.0/Architecture/Obje Part 1: Humanoid animation (HAnim) architecturectInterfaces.html#Humanoid
HAnim architecture specification is abstract and must be implemented by other specifications. Thus you have to look in X3D Architecture specification for corresponding X3D details.
Corresponding X3D Architecture specification is
1. X3D4 Part 1: Architecture and base components, 26 Humanoid Animation (HAnim) component, clause 26.3.2 HAnimHumanoid

As you can see, this node signature does include /metadata/ field.
As you can also see, there is no /value/ field.
Of note is that there is an HAnimHumanoid /info/ field for metadata information, an MFString array of “name=value” pairs. Very clumsy to use in practice. The X3D4 Architecture notes in 26.3.2 the preferred alternative approach:
1. Metadata values from the info field can be equivalently encoded via MetadataSet containing related X3DMetadataObject nodes.
Conversions are provided by X3dTidy cleanup stylesheet, and converted examples online. (Not finding this information in X3D Scene Authoring Hints, will add it.)

Reviewing X3D Tooltips confirms this answer to your question, along with convenient links to clauses in both specifications. (Each of the node names e.g. HAnimHumanoid links to the current X3D Architecture CD1 clause.)

Note how stiffness=[0,0,0]was given as a list in brackets, rather than a tuple value in parentheses stiffness=(0,0,0) as might be expected for SFVec3f, and so this is a useful diagnostic.
However the actual specification type for stiffness is MFFloat. (This was a mantis issue, might we tighten it to SFVec3f, but decided to keep it MFFloat in case more-advanced kinematics engines were someday of interest.

23 DEC 2021, carlson brutzman
- restore type of HAnimJoint stiffness field as MFFloat (vice SFVec3f) to match
specification, since more-advanced kinematics engines might someday hold interest.
This fixed the stiffness error.
However, next got a surprising conversion error (which might have been what you experienced originally):

This conversion should have been metadata=MetadataSet etc. Looks like the field name for the HAnimHumanoid MetadataSet was not specified incorrectly, the automatic conversion by X3dTidy did not apply correct containerField value.
I have added a rule to X3dTidy.xslt that looks for this case (for either representation, X3D3 or X3D4) and corrects it. I have added a similar diagnostic rule to X3dSchematron checks.
All affected HAnimHumanoid scenes have been updated and are now getting compiled correctly by Python.
All changes checked into subversion. Further regression testing continuing, website uploads to follow.
So again thanks for exposing this issue. Pretty complex but resolvable. Once again the strict nature of Python aided us in achieving high Quality Assurance (QA) for X3D.
Happy holidays with X3D! 8)
all the best, Don

I believe I checked the right standard, here:

And neither value or metadata is a field????
Seems a bit strange.

Also, check to make sure stiffness is assigned the right data structure (between list and tuple). And no, iOS, I do not want “Tupperware” for the second time. We need more women mathematicians (sorry for any stereotyping). On that subject, I wonder what coordinate system crocheted hats use?

Okay, now I seem to be having a similar problem between my python serializer, X3dToPython.xslt, and probably other serialized stuff. I couldn't figure out how to fix the stiffness issue in X3dToPython.xslt, but hand-editing saved that on this particular python file (python/net/x3djsonld/data/JinLOA4.py). Other JinLOA's still have lists with Don's generator.
I believe the main change I am dealing with is metadata vs value containerFields. See JSON diff below. I'm not seeing relevant changes to X3D JSON schema 4.0. Does something need to be upgraded in X3DUOM or X3D JSON schema? I'm not seeing a value field in HAnimHumanoid.
