Subject Re: [Axis2] Google Summer of Code - Binary XML Serialization - Weekly Schedule
Date Thu, 14 Jul 2005 03:55:28 GMT
Hi Dennis;

Just to add some info, we are thinking about adding the binary support
by writing a impl for
Stax readers and writers works on top of binary protocol. As Axis2
reads and writes using stax .. will not notice any differance.

 My original proposal is located online at
 My project mentor for this project is Eran Chinthaka.

Most of the work this week will be towards expanding supportedlanguage.

If time permits, I will also start on a third parser.
