[x3d-public] FW: Forgot what we did Re: ProtoInstance for material in X3DUOM.

[John Carlson]

Roy, read this.

Grrr.   What if all I have left over from the big crash of 2018 is binary code, X3DUOM and some X3D JSON files and the abstract specification is lost?   How do I reconstruct a JSON schema in that case?   Things should be made explicit and self-documenting for archival purposes.   We can't have stuff floating in people heads.

Yes, I have a disability.

If we have a class of nodes that goes everywhere, then let's give them an interface and I will hard code it in the JSON schema generator.  I don't like it though.  I believe I'm already hardcoding several statements.  Instead of putting the logic in the object model where it belongs, we’re putting it in ALL our tools.

Perhaps I should have been plainer.  I actually am not adding ProtoInstance to -material, I am adding it to

    "-X3DMaterialNodeSFNode": {
      "type": "object",
      "properties": {
        "Material": {
          "$ref": "#/definitions/Material"
        },
        "TwoSidedMaterial": {
          "$ref": "#/definitions/TwoSidedMaterial"
        },
        "ProtoInstance": {
          "$ref": "#/definitions/ProtoInstance"
        }
      },
      "additionalProperties": false
    },


For the time being.   I would like to add it to:

    "-X3DMaterialNode|X3DAnyNodeThatGoesAnywhereSFNode": {

Instead, which would actually be acceptableNodeTypes=”X3DMaterialNode|X3DAnyNodeThatGoesAnywhere” on the field named “material” in X3DUOM.

I can certainly hardcode “X3DAnyNodeThatGoesAnywhere” in the JSON schema generator, no problem.  It will go on ALL acceptableNodeTypes and appear on most if not all -SFNodes and -MFNodes.   For the time being.   Is that acceptable?  Alternatively, I may get a list of nodes that go anywhere, and add them to all -SFNode and -MFNode fields, without adding the long and unwieldy “X3DAnyNodeThatGoesAnywhere.” I still don’t know why I’m coding Object Model-like stuff in the JSON schema generator though.

I thought we already had an interface that went everywhere, and we discarded it????  Roy?

John
