Hi Philipp, Not an expert either but from what I know, what you expect seems to be possible. I think the best way for you to learn about hooks - apart from the official doc <https://svnbook.red-bean.com/nightly/en/svn.reposadmin.create.html> - is to look at the templates created by default when you create a repo ("svnadmin create"). You can also find some examples in the SVN repo: https://svn.apache.org/viewvc/subversion/trunk/tools/hook-scripts/ https://svn.apache.org/viewvc/subversion/trunk/contrib/hook-scripts/
In your case, the way to go seems to be a *pre-commit* hook. * For the commit message restriction, look at the examples. * As for the "can do / can't do", the standard way would be to enforce "path-based authorization <https://svnbook.red-bean.com/en/1.8/svn.serverconfig.pathbasedauthz.html>", but it isn't flexible at all because it doesn't support wildcards. I would personally recommend the use of "svnperms <http://svn.apache.org/repos/asf/subversion/trunk/tools/hook-scripts/>" which should do what you want: advanced path-based control (with regular expression support). I have a kind of "framework for hooks" hosted on GitHub <https://github.com/justinmassiot/svnhooks>, this may help as an example.
