Having worked through the ZClasses tutorial and howto examples, I now have a design question. Being very inexperienced with Zope, I would like to create a catalog of links that automatically updates itself when new links are added. I suppose the best way to do this is to inherit from CatalogAware and ZObjectManager. CatalogAware (as I understand it) allows me to automatically update itself and ZObjectManager allows me to embedd sub-links. Then I can add a search interface to find links. My Links tree would look something like: /Links + History + US History + European History + Languages + Dutch + English Does this sound like a reasonable way to keep a database of links? Does anyone have better suggestions? I prefer not to store them in an external DB (since I'm learning Zope). One other thought, instead of ZObjectManager perhaps I should inherit from Folder? Thanks, John
