Each node is a single notecard, which can contain an arbitrary amount of information. Like Guide and Intermedia, scrolling is used to display different parts of the node. When following a link the destination node can be displayed in a new window, possibly overlapping the old window. Users can open as many windows as they want, thus generating a messy desktop.
NoteCards has over 50 specialized types of cards, for applications that need special data structures, with a special layout.
Links are typed connections between cards. The type is a label chosen by the creator of the link, and can indicate the kind of relation between the source and the destination node.
The browser card shows a graphical overview of the link structure of the hyperdocument. Different link types are indicated using different line patterns.
Cards can be nested hierarchically, using a FileBox. FileBoxes are special cards and can contain both FileBoxes and other NoteCards.
