[x3d-public] X3DJSAIL/X3DJSONLD.java how to fix JsonConversion for modules.

[John Carlson]

I know I am not presenting as well as I can. In summary, X3DJSONLD.java 
should look at containerFields and defaults (perhaps), and 
X3DLoaderDOM.java should look at DISEntityTypeMapping (children of 
DISEntityManager) and children of LoadSensor.  This will be a good start 
at finishing off X3DJSONLD extensions to X3DJSAIL, and likely enhance 
DOM document loading in X3DJSAIL.

==============================

I found an XML pretty printer.

The main differences between JsonConversion.java [ XML DOM output] 
(HWP.x3d, previously posted) and HelloWorldProgramOutput.x3d appear to 
be containerFields and default values.   ContainerFields are well known 
that I strip those out in X3DJSONLD.java...should be an easy fix.

HWPJSON.x3d is pretty printed X3D XML output from JsonConversion, and 
HWPO.x3d is pretty printed HelloWorldProgramOutput.x3d (see xmllint 
commands below).

Note that DISEntityTypeMapping is in the XML DOM output from 
JsonConversion.java (HWP.x3d), perhaps there's a problem with X3DLoaderDOM?


LoadSensor children don't seem to be handled in X3DLoaderDOM?


I can post output from running JsonConversion.java, if desired, it's 
kind of long.  I have already posted how to compile and run.
