Subject Re: GSoC application
Date Tue, 22 Apr 2008 08:21:39 GMT

The results are out, unfortunately no student has been selected for the 
Commons Configuration project, the slots for GSoC projects went to other 
Apache project this year.

I'd like to thank you for your application, it looked very promising and 
I think I would have liked mentoring it with you.

Good luck for your studies.

Emmanuel Bourg

> May 27 - August 11: Coding Phase. In this 11 weeks, plan to implement
> 3 new formats: JSON, YAML, and OGDL, which means about 3-4 weeks per
> format. Write documentation and unit tests.
> August 12 - August 18: Revise some minor errors. Complete some documentation.
