How have you structured the tagging functionality? What kinds of analysis can be done on the collective set of tags for a pbwiki?

I am interested in accessing the large number of tags that have been created on a wiki for a university composition course in order to do some analysis, including clustering and looking for emergent semantics. I wanted to know how pbwiki manages the tags in its underlying database, whether I could download the tags for analysis using another app, in what formats I could download them, what associated information (i.e., users and pages) I could download with them, and so on.

The wiki I'm interested in analyzing is wyrd2thewiki.pbwiki.com.

Thanks for any help or insights you can provide.
