[x3d-public] X3D JSON Schema updated for axis++ defaults

[Brutzman, Donald (Don) (CIV)]

HI John - please clarify.

JSON encodings are provided for every example, links are in upper-right corner of page you've identified.  Specifically found at

  *   https://www.web3d.org/x3d/content/examples/Basic/StudentProjects/Trebuchet.json

If the file is failing JSON lint, or JSON schema validation, then please identify the scene error precisely and let's pursue that fault.

Good luck with continued testing of JSON schema validation for X3D.

all the best, Don

Please provide validatable JSON (Trebuchet.json) from the above website.  Thanks!

(throwing 3 darts in hopes of hitting a bullseye--or at least 3 triple 20's).

Note that schema updates have been applied.

Updated JSON validator here:  http://coderextreme.net/X3DJSONLD/src/main/html/validator.html

I suggest grabbing the X3D JSON schema from here:

https://github.com/coderextreme/X3DJSONLD/blob/master/src/main/schema/x3d-4.0-JSONSchema.json

and testing Trebuchet.json as downloaded from the first link with XMLSpy.

Then reconsider the request in your original message on this thread.

We probably already discussed this exact thing quite some time ago.  Luckily we have a good email thread to go back to should this discussion arise again.

This one looks like a good test for X3dToJson.xslt to produce a validatable JSON.  So far, the JSON is failing my tests.

https://www.web3d.org/x3d/content/examples/Basic/StudentProjects/TrebuchetIndex.html

I suggest doing a validation with XMLSpy of the X3D JSON file to test the X3D JSON schema's power.

Comment validation removed.  Did not find any examples.   Please test.

Thanks!

Can we put this and any outstanding JSON schema modifications on the agenda for next week?

2. Saw a documentation problem:  USE nodes can't indicate anything besides the @USE value (except for containerField value for relevant parent-child relationship in XML encoding).  So your following guidance about comments is not portable outside of JSON.
    "RigidBody": {
      "type": "object",
      "oneOf": [
        {
          "type": "object",
          "properties": {
            "@class": {
              "type": "string"
            },
            "@USE": {
              "type": "string"
            },
            "-children": {
              "type": "array",
              "minItems": 1,
              "items": {
                "type": "object",
                "properties": {
                  "#comment": {
                    "type": "string",
                    "$comment": "#comment statements are the only allowed in -children node when using a USE field"
                  }
                },
                "additionalProperties": false
              }
            }
         },
          "required": [
            "@USE"
          ],
          "additionalProperties": false
        },
