Hi,
Gustavo (on cc) and me have been analyzing how to split Kimchi Virtualization layer form its Base web framework. We would like to leverage all infrastructure kimchi base framework provides (URI routing, error handling, i18n, authentication, API validation, plugin tabs loading) in other projects, and contribute this back to kimchi-ginger project.
The general idea for the web framework is that it provides basic UI with login and tabs menu, and each plugin installed extends the menu with some tabs.
We started by making kimchi a plugin, like ginger is. We are way advanced on that and already have most of kimchi's UI running as a plugin over an almost fully running base web framework.
Ginger needs minimal changes, mainly on import statements. We can provide changes needed back to ginger too.
Currently, we are splitting kimchi specific stuff like this way: (after renaming the dir src/kimchi to src/backend *)
* we are using the name "backend" just for disambiguation from virtualization layer (plugins/kimchi). We will need to define a better name for that basic framework. One suggestion is to call it "wok", the base where kimchi is cooked.

The remaining generic stuff on the "backend" side, usable or already in use by other plugins, would be:

We don't want to make this a too long e-mail and lose the focus on the idea. We have further technical details to discuss in a follow up.
Please let us know your thoughts on that, any directions and requirements you have on this, and how could we proceed with that plan.
I really favor the idea of splitting http server framework with applications kimchi manages. Basically, I wish we can refer the framework of Django to isolate cache, session, authentication, DB access to framework, and other application related to applications(or we call it plugin). From my view, kimchi web server current manage 3 types of application--host management application under host tab(host stats collection, software repository configuration, sos), virtualization, platform specific application (ginger). Some host management application listed above, like swupdate.py, repositories.py, netinfo.py,and screenshot.py is related to virtualization. I would suggest these part to be moved out too. Bricks welcome:)
