[x3d-public] Eye trouble; standard JSON and standard Python both

[John Carlson]

>From json-schema.org:

"The Path to Standardization

The JSON Schema project intends to shepherd all four draft series to RFC
status. Currently, we are continuing to improve our self-published
Internet-Drafts. The next step will be to get the drafts adopted by an IETF
Working Group. We are actively investigating how to accomplish this.

If you have experience with such things and would like to help, please
contact us!"


So perhaps there's not much motivation for tool developers to migrate their
tools to the new version?
