[x3d-public] Efficient XML Interchange (EXI) for JSON - W3C working draft

[John Carlson]

To be fair, I ran the conversion on the exificient demo site and got essentially the same results.  Perhaps people have already tried that.

How does XML fair?

I took out the performance stuff as well.   There may be an issue with my coding, but I tried to follow the example, taking out the unnecessary stuff (which may have been necessary.  It would be interesting if more people tried their JSON files to see if the JSON conversion works.  Obviously, the XML, being text, may fair much better in tests.  Perhaps converting JSON to XML first is the way to go.
