Webview<br />

Webview provides a tree-based structural display of part of the document. It shows <strong>in</strong>dividual document<br />

components and the l<strong>in</strong>ks between them. Unlike the Docuverse, <strong>in</strong> addition to structure it displays multiple<br />

attributes of the components. The local vic<strong>in</strong>ity currently shows parents, sibl<strong>in</strong>gs, and descendents. Webview will<br />

also show l<strong>in</strong>ks to nodes that are far away, e.g., cross references to documents <strong>in</strong> a distant area of the document<br />

space.<br />

Figure 2 shows a four-level subtree. Color is used <strong>in</strong> this view to show component type -- e.g., comment,<br />

objection, graphic, etc. Color can alternatively be used to render the age of the document as was the case with the<br />

Docuverse. We are currently explor<strong>in</strong>g how multiple attributes might be depicted us<strong>in</strong>g shape, color, saturation,<br />

texture etc. The displayed tree is developed dynamically, and the user may traverse up or down the tree by<br />

click<strong>in</strong>g on conta<strong>in</strong>er nodes, which become the new root node. Beyond type, the node label identifies the owner<br />

and creation date or title of the node.
