Link Model vs. Browsing Model: Semantics vs. Navigation

• Link model: semantic relationships between data items
• Browsing model: hypertext behaviour of links (i.e. navigation)
• Analogous to markup language vs. style sheet language
• Necessary for presentation on various devices

Link model example:

<link xlink:type="extended">
 <locator xlink:type="locator" xlink:href="rep.xml#xpointer(abstract)"/>
 <locator xlink:type="locator" xlink:href="tec-doc.xml"/>
 <arc xlink:type="arc" <--! xlink:show="new" -->
  xlink:title="new information"/>
</link><

Browsing model example:

[xlink:title='new information'] { show: new }
