[x3d-public] [x3dom-users] simple X3D -> JSON -> X3DOM, D3.js

[Leonard Daly]

John,

Are you aware that Don Brutzman did an initial JSON converter using a 
style sheet to go from .x3d -> x3d-json. The description is at 
http://www.web3d.org/wiki/index.php/X3D_JSON_Encoding. The code is at 
sourceforge (link in the wiki page), and has been added to X3D-Edit.

Yvonne Jung developed a JSON loader for X3DOM. You can see an example at 
http://www.x3dom.org/x3dom/test/functional/flipper.html.

The initial work was completed last October. The wiki page lists several 
considerations. The Consortium is considering standardizing the JSON 
format. We would like everyone's comments and thoughts on the work that 
has been done, particularly where there are shortcomings or failures.

Ultimately, the license choice is yours; however, which one you choose 
depends on what you what to happen with it. A very public use license 
will allow others to take what you have done and incorporate it into 
anything and resell it. If you are not careful with the name, your name 
could be co-opted too. If you want contributions to remain as 
open-source, than a GPL-type license might be the right choice. 
Wikipedia has a good starting page on software licenses: 
http://en.wikipedia.org/wiki/Software_license (Free license comparisons: 
http://en.wikipedia.org/wiki/Comparison_of_free_and_open-source_software_licenses). 
Until you figure it out, I recommend that you be restrictive and only 
let people use it exactly as is (since you already put it out for public 
use).
