Once the user has fi nished editing, the page is rendered into a user-
friendly viewing format via a wiki template, as shown in Figure 17.9(a). As
can be seen in Figure 17.9(b), the system renders semantic tags (in this case
showing that CD4+ T-cells have been associated with the assertion). In
addition, via an ASK query, connections to other assertions in the system
are identifi ed and dynamically inserted at the bottom of the page, in this
case identifying two child observations that already exist in the system.
All assertions are created as part of a 'project', normally focused on a
disease of interest. In some cases disease knowledge was retrospectively
entered into the system from legacy documents and notes and subsequently
further expanded. New projects were initiated directly in the wiki,
following discussions on the major elements of the disease by the scientist.
