[x3d-public] Suggestions for validation

[John Carlson]

I may have shared a model, but we are currently working on making X3D-Edit
better because it provides the most features.  I think that means only XML
is validated at this time.   If the SAI (X3DJSAIL, x3d.py) provide
additional validation, they should be integrated (make CommandLine easy to
use in a nice package, where I don’t have to set up classpath, etc.)
 perhaps think about compiling into an executable or script, or building
CommandLine into X3D-Edit.   Also, I have half-baked JSON reading tools in
Java and Python.  I spent some time getting X3DJSONLD.java working, but i
got hung up on quotes and “container” fields in JSON, we could potentially
provide JSON validation in Java or Python without schema (well, the
grandaddy XML schema).  Sigh!   For x3djsonly.py JSON to Python conversion,
that work needs to be extended past a single test file.  The scripts for
that are mostly written, but roundtripping needs to be written.

I am a bit concerned about the memory being used to validate as I’ve seen
memory consumption in one of my perl scripts go to 11GB for a Humanoid, and
it’s not even LOA4.

Terabyte SSDs are sounding really attractive right now…
