Hello, I am a software engineering PhD student. I am currently performing and empirical study in which I am studing software metrics on the Rails project. I am analyzing the code of Rails 2.3 for this study.
I need your help because for this study I need to split the source code in several modules, considering that a module is a file, a set of files, a directory or a set of directories containing a standalone piece of code that provides specific and tightly coupled functionalities.
Given this definition and the architecture of Rails 2.3, what would be the modules for you?
