We have finally made it to publish our Efficient XML Interchange (EXI) parser as Open Source. The implementation is called WS4D-uEXI. The ‘u’ stands for ‘micro’ and yes, this means it has really small footprint. uEXI is designed to run on WSN/6LoWPAN mote class devices with only tens of kB RAM and ROM. You will find some more information, documentation and of course also the code on the WS4D-uEXI project website at Google Code. Fell free to join the project and contribute!
