<p>My first task will be downloading the 2020-12 JSON schema, and
reviewing it against draft07 JSON schema, to see differences.
Then, I will pursue X3D JSON 4.0 schema generation using python
(again). We had decided before to use draft07, because no tools
were available to pursue 2020-12 or 2019-09 JSON schema in Java.
Now there is one tool to do validation (see below). One reason I
liked the draft07 approach is that the Python JSON validator I
use, fastjsonschema, does not support 2012-02, and I already have
draft07 working with multiple versions of X3D JSON schema in the
same program (note that JSON schema has been converted to python):</p>
<p>```</p>
<p>import sys<br>
import json</p>
<p># the below packages are available in X3DJSONLD, they are X3D
JSON schemas converted to python:</p>
<p>import schemaparser30<br>
import schemaparser31<br>
import schemaparser32<br>
import schemaparser33<br>
import schemaparser40<br>
<br>
jsobj = json.loads(sys.stdin.read())<br>
version = jsobj["X3D"]["@version"].replace(".", "")<br>
try:<br>
if version in [ "30", "31", "32", "33", "40" ]:<br>
eval("schemaparser"+version+".validate(jsobj)")<br>
except:<br>
print('Invalid')</p>
<p>```<br>
</p>
<p>At sometime, I think independent X3D JSON schema generation would
be appropriate. I did state that converting X3D XML Schema to X3D
JSON schema with XMLSpy was probably infeasible due to field and
comment prefixes in X3D JSON--You will have to provide hooks in
XMLSpy to achieve this, or ask for more options to XMLSpy (which
is possible) or XML schema. I suggest running a test to see if
the X3D JSON Schema produced will validate the 4000 examples
generated by X3dToJson.xslt. The Web3D Consortium may send my
sample X3D JSON schemas to Altova to meet requirements of X3D JSON
Schema, with the requirement that their schema generation product
will meet the Web3D Consortium's IP requirements, that is, we want
everyone to be able to use the schema used, whether they have
XMLSpy or not.<br>
</p>
<p>What I'm kind of confused about is whether we'll provide JSON
validation with X3D*SAIL or /JSON schema/+/validation tools/ or
both. I think having separate implementations would be a good
plan. I am fairly confident that Don committed to supporting X3D
JSON import into X3DJSAIL, but not using X3DJSONLD.java. In
particular, he suggested translating JSON to DOM document was not
the preferred approach, but he was open to doing X3D JSON import
with Saxon. I didn't ask him how he was going to get Saxon output
into X3DJSAIL--would you like to comment, Don? I know I haven't
fully elucidated my thought processes around X3DJSONLD.java. Why
did I choose to convert to DOM? Probably because I didn't see
myself writing or generating X3D*SAIL for ECMAScript, I already
tried to write X3DPSAIL and es6x3d, I merely don't seem to have
the brain power or time. I need to support my old tools, or
transfer to one that has wider demand. There are other issues
like competing with X3DOM and X_ITE--I chose to play nice. I
didn't want to support 2 different SAI solutions, when X3DOM and
X_ITE were already far down that path.<br>
</p>
<p>Here's the code in X3D4 JSON schema to support multiple versions:</p>
<p> "@version": {<br>
"pattern": "^(\\s|\\S)*$",<br>
"enum": [<br>
"3.0",<br>
"3.1",<br>
"3.2",<br>
"3.3",<br>
"4.0"<br>
],<br>
"default": "4.0",<br>
"$comment": "SFString inputOutput",<br>
"type": "string"<br>
}<br>
},</p>
<p>So I am fairly confident that the new 4.0 schema will be able to
support older versions. I would ask about XvlShell though. I
think we may have some old files that have that node.</p>
<p>I also note that one can change the @version property
(inputOutput). This seems counter-intuitive.<br>
