X3D JSON Encoding

Preliminary notes on the creation of an X3D JSON encoding.

• This page is to understand the conversion process so that a high-quality encoding definition can be created
• Don Brutzman started a thread on the X3D-Public list.
  • Initial message [1]
  • July's thread listing [2]

Conversion Issues

• How to convert attribute names to distinguish them from child elements
• Handling of container elements
• Creation of JSON elements with datatypes appropriate to content (e.g., integer, float, strings, etc.)
• Inclusion of XML namespaces
• Handing of comments in the source
  • {LD} I don't see an issue of dropping comments during conversion. This is not suppose to be a conversion of files to maintain an archive, but a conversion for use. JSON does provide comment mechanisms.
• Don reported that self-closing tags are not missing from his test runs
