Developing plugins' system

Hi,

I’m working on a plugin’s system. There is a Core plugin that is a main one and many dependent plugins that use Core code base. Core plugin is like a framework for other plugins. The main idea is like at Jetpack plugins system.

The question is what is a proper way to upload these plugins to WordPress plugins repository? Is there a correct order? I mean that Core plugin doesn’t do anything seeable but another plugins will not work without Core. And if I will send Core to plugins’ repository they can say that “What is it for?”, but if I send anothe dependent plugins first plugins will not work without Core.

Did anybody do such uploads before?

Thanks!
