ZTopics allow you to create a hierarchical, topical view of a ZCatalog. A ZTopic manages a set of search criteria it uses to determine it's "contents". Nested ZTopics can be made to refine their parents and exclude their children. This feature makes it quick and easy to build directories to content.
