[x3d-public] Is https://www.web3d.org/specifications/java/examples/HelloWorldProgramOutput.json valid?

[Brutzman, Donald (Don) (CIV)]

Hi John.  All of the JSON that you find is produced by our X3dToJson.xslt
stylesheet, which hopefully meets all patterns we derived and documented at

 

*	X3D to JSON Stylesheet Converter
*	https://www.web3d.org/x3d/stylesheets/X3dToJson.html

 

Well-formed JSON can be checked.  All of our online examples have a link to
check via JSONLint, though tonight it is saying "unable to connect" (while
providing plenty of advertising).

 

*	X3D Example Archives: X3D4WA, X3D for Web Authors, Chapter 01
Technical Overview, Hello World

/HelloWorldIndex.html
*	upper-right inset box of links:
<https://x3dgraphics.com/examples/X3dForWebAuthors/Chapter01TechnicalOvervie
w/HelloWorld.json> .json (
<https://jsonlint.com/?json=https://X3dGraphics.com/examples/X3dForWebAuthor
s/Chapter01TechnicalOverview/HelloWorld.json> check)
*
https://jsonlint.com/?json=https://X3dGraphics.com/examples/X3dForWebAuthors
/Chapter01TechnicalOverview/HelloWorld.json

 

If there are mistakes in our X3D .xml -> .json pattern or the conversion
stylesheet, they can be fixed.

 

Strict JSON validation isn't possible until a JSON Schema is approved.  If
you think that there is a Java-based implementation of the draft JSON Schema
that is mature and stable enough to deserve our time, we can try adding that
to our various build tools for X3D Example Archives and X3DJSAIL.

all the best, Don

Don, if

 

https://www.web3d.org/specifications/java/examples/HelloWorldProgramOutput.j
son

 

is supposed to be valid X3D JSON, please inform me.  Thanks! 

 

To ensure that -value is not a field of Shape in JSON, I have added the
following exception in x3djsonld.py.

 

 

        if parent in ("Text", "Shape") and key in ("value"):  # don't have
value yet, sorry

            # do value later

            raise "-value not a supported field of Text or Shape, try
-metadata?"

            continue

 

I can revert the code if necessary.  I'm trying to follow the standard as I
see it.

 

If -value under Shape is correct, then X3DJSAIL needs to support addValue
(as I have it in Java) or setValue.  That's my opinion.

 

John
