Trunk folder for Repository?

Question

I am hashing out our structure for Subversion and have the standard structure that I think most people use which is using one repository and multiple folders for each project:

MainRepository
    Project1
       branches
       trunk
       tags
    Project2
       branches
       trunk
       tags
..and so on

My question is, do I need a trunk, branches, and tags folder for the root MainRepository? Why would you if you're checking out from the trunk of lets say Project1. I don't know if I need one or why you'd need a trunk folder or others in the actual root of the repo.

MainRepository
    Project1
       branches
       trunk
       tags
    Project2
       branches
       trunk
       tags
    ...
trunk
branches
tags

Answer 1

You actually don't 'need' it. It's up to you (and your projects) what you need. A trunk folder in the root makes sense when you use a repo for each project instead of one repo for many projects, in which case you don't need a trunk folder in the root folder.
