Automatically add svn keyword properties for new files (server-side)

I want to add svn properties (like svn:keyword=Id Date Rev Author) to files upon commits of new files.

For this to work there may be two main options:

1. Client-side: altering the autoprops in the svn client configuration
2. Server-side: do some magic with commit-hooks

The client side is not always desirable, as control over the client set up is needed. I want to solve this on the server. How can this be done.
