[x3d-public] ANNOUNCE: x3djsonld.py X3D JSON to Python (Load and Export) Pre-Beta Testers wanted

[John Carlson]

Note that I only have one more day/night to work on this, and then I may
not be able to work comfortably due to health issues.

So if you like the idea of using python and x3d.py to transpile JSON into
python, know JSON and python, now’s the time to take action and help iron
out bugs!

The alternative is to use X3DJSONLD in another language (ECMAScript, Java,
and C++) to convert JSON to XML, then go to Python using X3dToPython.xslt.
  X3DJSAIL+X3DJSONLD.java offers the opportunity to do this in one program,
but you’ll have put in some elbow grease to accomplish this.   There are
examples of using X3DJSONLD.java to accomplish this for other encodings.

But right now, your opportunity is with x3djsonld.py.   See below link
included

Note: depending on your python installation,
You’ll have to do:

from x3d import *

or

from x3d.x3d import *

at the top of x3djsonld.py and generated python program at the bottom of
x3djsonld.py
