Open Stack

Hi,

I really want your help. I am doing a research of finding the pattern of open source software development.

It is a pity that I have no experience in contribution on open source software. What kind of code files are usually modified by

many developers and what kind of files are usually touched by one person. And in order to ensure high quality, what’s your opinion

about these two kind of files? For example, the code ownership….

Thank you very much!

Regards
