<p class="MsoNormal">Don, I am developing these ideas. I have to talk to a teddy bear to develop them. There are new thoughts being introduced. The previous email was to get the engine going.<o:p></o:p></p>

<p class="MsoNormal">Don, JSON has a specification and a standard. There is no Classic VRML schema, just a grammar. Similarly, there is JSON grammar that is standardized. If you point at the XML Schema for classic VRML, why can’t we do the same for JSON?
It’s been shown that we can create DOM documents from JSON documents, why not validate the DOM documents against XML Schema? If someone could point me at a way to validate DOM documents in Java with XML Schema, it would probably take me 1-4 days to start
validating X3D JSON with XML schema. I think that having a single schema, and 2 object models is OK! I’ll just have to figure out how to validate DOM documents on the web. The biggest win of putting JSON into DOM documents is that potentially, all the
goodness of X3D-Edit could be applied to the JSON documents (I just realized this. I now feel like a genius!). I’ve basically been a DOM proponent for quite a while now, all my X3DJSONLD.* programs use it except for x3djsonld.py (poorly named). I’m not
aware that DOM is popular in Python.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Since the last JSON schema draft proposal was 2020-12, I have not seen any progress on core JSON schema validation standardization. If you want me to try some newer implementations, which ones? Your requirements are probably stricter
than mine. If we wait for a JSON schema standard, we’ll be waiting for implementations again. Probably by the time the JSON schema standard comes out, JSON will be deprecated (note that Microsoft is highlighted on the JSON schema page, not a company strong
on open standards).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Perhaps DOM document validation with X3DJSAIL (by way of scenegraph) still needs some effort? Maybe we can skip that with a DOM XML schema validator? I realize we need teamwork to finish off the X3DJSAIL/X3DJSONLD pair. For me, to get
access to X3DJSAIL outputs and validation without resorting to XML or Java source code, and for you, to get X3D JSON converted to whatever you target.<o:p></o:p></p>

<b>Specifications Synchronization</b>. Update, review, implement and advance all corresponding X3D specifications for file encodings and language encodings, continuing rigorous attention to detail through Web3D Consortium, W3C, US INCITS H3, and ISO/IEC standards
development organizations (SDOs).<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l14 level1 lfo14">
<b>Implementations</b>. Provide a technical forum that encourages the greatest possible development for functionally complete X3D4 applications, authoring tools, and model converters such as Blender and MeshLab. Pay special attention to implementations using
Humanoid Animation (HAnim), glTF model import, Web Audio API and MIDI 2.0 capabilities for integrated spatial auralization, projective texture mapping, HTML5 integration, XML, JSON/JavaScript, Java, Python, C/C++/C#, compressed binary formats, and additional

<b>Innovation Foundation</b>. Show how Extensibility mechanisms for X3D can implement new capabilities in a standards-compatible way. Much is possible, model correctness is validatable, and few barriers to exploration exist.<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l14 level1 lfo14">

<b>Past as Prologue</b>. The X3D Working Group carefully follows Web3D policies and procedures, integrating much public/private comment that is well documented in X3D email archives and Mantis issue tracker. Both backwards compatibility and forwards extensibility
have been carefully preserved throughout, enabling effective reuse of every VRML97 and X3D model for the past quarter century. Seventh in a specification series starting with VRML97, successful completion of the X3D 4.0 Architecture once again proves that
this collaborative process is effective.<o:p></o:p></li></ul>

<b>Innovation</b> by emphasizing X3D extensibility mechanisms: Inline, Script, Prototype, software libraries supporting source-code implementations that generate X3D, etc. etc. New candidate nodes (such as
<i>Image Atlas</i>) that rise to the level of broad usefulness can be formally considered as contributions to Web3D Recommended Practice.<o:p></o:p></li></ul>
