<p>Main issues in output JSON seem to include</p>
<p>1. Missing arrays</p>
<p>2. Missing keys with a leading "-", like "-appearance",
"-material", "-children", "-geometry", "-texture", "-fontStyle"<br>
</p>
<p>3. I don't do comments yet.</p>
<p>Attached JSON import/export module attached, with sample JSON
input.</p>
<p><br>
</p>
<p>I will dig a bit into the x3d.py code to see what's happening.</p>

<p class="MsoNormal">Sure enough, searching for “class _
X3DField” in x3d.py reveals two abstract class definitions,
ouch! That’s more like multiple personalities that multiple
inheritance…<o:p></o:p></p>

<div>
<p class="MsoNormal">Python does support multiple
inheritance, but these fragments are not an example of a
multiple-inheritance situation -- rather, the later class
definition -- where _X3DField is a subclass of _X3DNode,
overwrites the earlier class definition. <o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">In the x3d.py file, only three
classes are defined as direct subclasses of object:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">class _X3DField<o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">So I think the operative question is
whether it is a design intent that _X3DField also should
be a subclass of _X3DNode. I judge the answer is no,
since that would include support for DEF, USE, and
metadata. In that light, the second class defintion for
_X3DField would be regarded as a bug, to be corrected by
modifying the X3duomToX3dPythonPackage.xslt stylesheet.<o:p></o:p></p>
