TopicType

TopicType of all TopicTypes

Documentation

The TopicType is the root of the type system of the WikiWorbench. Every WikiTopic has got one or more TopicTypes. TopicTypes always define a DataForm, where a type indicates the properties and use of the form being attached to a topic.

TopicTypes overcome Foswiki's limitation to only allow one form to be attached to a topic. If you'd like to attach a second form to a topic, create a new DataForm that mixes two others and indicate this by merging the resulting TopicType properties. This procedure is the recommended way to derive new TopicTypes from existing ones building on top of them, e.g. by augmenting a CategorizedTopic with additional formfields.

TopicTypes have a special property that you might use to indicate a special way of derivation by means of inheritance. There is no real inheritance in Foswiki but the way of thinking when dealing with objects and types can be clarified this way.

When you start writing a WikiApplication, first think of the data objects you will need and create TopicTypes for each.
