The data for the analysis of user behavior is retrieved from markup embedded in the portal pages.
The aggregator associated with the page formats the data, so that it corresponds to the requirements of the external analytics service to which it is finally submitted. By changing the Javascript the administrator can change the information that is retrieved from the page and submitted for analysis.
The data is represented as a microformat in the portal page HTML
DOM tree and tagged with CSS classes. An example of such microformat
is:
<span class="asa.portlet.title">My Portlet</span>
