<p>You'll need a SAI library to do fullest verification. We would
have to dig deeper in the JSON schema standard to discover any
additional constraints that can be added.</p>
<p>This is why I spent a lot of time incorporating JSON import into
X3DJSAIL. I suggest you bring this up with the X3DJSAIL folks,
that you want JSON import into X3DJSAIL, x3d.py, etc, I don't
think it's imperative.<br>
</p>
<p>I have 4000 or so examples already, thanks. Most of them pass
my schema, at least with a JavaScript validator. I have reported
the ones that don't, include the massive failure in the XMLSpy
converted schema (in python). We might be able to learn from it.
<br>
</p>
<p>.x3d files are not described by JSON they are separate encodings.<br>
</p>
<p>In the JSON schema, USE and DEF are unrelated, even in XML
Schema, I would purport.</p>
<p>We really need a good SAI validator, which is present in
X3DJSAIL, and x3d.py. This is why I have tried to de-emphasize
JSON schema, we have good libraries, if we want to add JSON
loaders to them. I do not feel that I am capable, and I have
appealed for help in constructing es6x3d SAI library.<br>
</p>
<p>I have spent most of my time supporting X3DJSAIL in Java, Python
and JavaScript.<br>
</p>
<p>There are scripts available that runs through the resources
archives and applies X3D 4.0 JSON schema to them.</p>
<p>Here is the main script, which you'll have to change if you want
to run it in a separate folder. There may be some tweaks with
open() that you will have to apply on Windows 10.<br>

<p>On Linux, you can run this from the python folder above, with the
command:</p>
<p>nohup python3 test.py 2>&1 > results.txt</p>
<p>I don't totally understand why things broke today, but I have
been getting it to work today.</p>
<p>Yes, there are problems with the HAnim files. I have basically
not reported on many of them. Would you like me to report to you
so you can fix them. I suggest writing a small program which
reads in HAnim .x3d examples into X3DJSAIL, and validating them.
This is already done with X3dToJava.xslt, but you have to know how
to compile with Java. So I recommend trying X3dToPython.xslt
instead.</p>
<p>This repository should help with validating with Ajv:</p>
