A category topic includes a data incarnation and a sensory representation. The appearance of the sensory representation is adjusted upon changes to the content of the data incarnation. In a described implementation, a title of the category topic is used to create the sensory representation as displayed on a user interface (UI). In another described implementation, the data incarnation includes a source definition and a keyword definition that jointly specify information that is to be included in the content. In yet another described implementation, at least part of a category topic may be shared with a destination user.
