Can anyone recommend a good binary XML format? It's for a JavaME application, so it needs to be a) Easy to implement on the server, and b) Easy to write a low-footprint parser for on a low-end JavaME client device.
And it goes without saying that it needs to be smaller than XML, and faster to parse.
The data would be something akin to SVG.
You might want to take a look at wbxml (Wireless Binary XML) it is optimized for size, and often used on mobile phones, but it is not optimized for parsing speed.
