SVN: create folder for older versions

Question

I'm new to version control systems, so forgive me.

My project consists of two small applications, as in their own SVN repositories. In addition, I have one common repository (svn: externals) between these applications.

When the new version is released, I would like to create a folder for this version (including sources, documents, etc.). The repository for one application should look something like this:

.UI
    . "old versions"
        . 1.0
        . 2.0
        . 2.5
    . trunk (current development version 3.0)

So my questions are:

• What is the correct name for this type of structure (in SVN)?
• How can I create it?
• Is it possible to freeze these old versions (prohibit making changes to this folder)?
• Are there any better ways to achieve this?

Answer 1

• "" - .
• "svn copy" - . .
• , "pre-commit hook" (. ).

pre-comit hook ( ), :

@echo off
SET SVNLOOK=C:\Program Files\CollabNet Subversion Server\svnlook.exe
SET GREP=D:\SVN\REPO\hooks\grep.exe

REM Prevent changes to tags.
("%svnlook%" changed -t %2 %1 | "%grep%" "^U.*/tags/") && (echo Cannot commit an update to a tag.>&2 && exit 1)

REM Prevent commits without comments.
("%svnlook%" log -t %2 %1 | "%grep%" "[a-zA-Z0-9]") || (echo You must specify a comment for all actions.>&2 && exit 1)

exit 0
