Sometimes, you want to refer from one place in the Zope Web site hierarchy to an object in another place. The reference should behave almost as the refered to object. I.e., you want something like a symbolic link in Unix. Shane's Symlink product allows you to do this. However, Symlinks are too good in behaving like the refered to object. Link and original are almost not distinguishable. Therefore, it is very easy to modify the link and accidentally change the original, too. That's why I consider Symlink a bit unsafe and recommend to use it only under very restrictive circumstances. References is very similar to Symlink. However, a Reference has its own id, title, icon and management facilities. Therefore, it can be quite easily distinguished from the target. I consider it safer. However, there are still some security weaknesses. See the README file in the distribution, for details. Download: <http://www.dieter.handshake.de/pyprojects/zope> Dieter
