[Zope] Calendar data

I'm implimenting a cool little calendar object I found round these parts. It uses attributes of it's parent folder to contain the dates and descriptions of items that it displays. So a key may be "2000/07/04' and the value would be "Fourth of July". i'd like to have a pretty dynamic method of entering these values from the web. I'm a little confused about how to do that. do i use an external python method? What form would it take? I suppose I could store the pairs in a text file or database and then read them in each time I opened the page. But it seems the first way is best. Is it possible? Security is more of an issue. How do I deal with that? Is this fun or what!! -mjm
