WikiRdf
From FOAF
A cool thing down the road would be a wiki which provides and RDF Export of its pages, using some categorization mechanism (i.e. some wikis use the convention of inserting wiki words that start with Category to indicate what applies to a page).
The wikiword categories and each page they apply to would be represented in the RDF graph. Its not clear to me yet how to mine the category wiki pages themselves for metadata (i.e. OpenDirectoryCategories) and include them in the RDF graph or map them from wikiword categories in some way (ontology?).
I have been futher thinking about this. A wiki which published recently added documents or diffs of older documents to a front "weblog" page and RSS page would make a great personal or team weblog. The wiki processor would render every page to look like a weblog page (i.e. customized with my links and stuff) so its not like a wiki. Similar to bloxom I guess.
An RSS of recent changes and of whole site would be available. A near-this-page tour would produce an RDF graph of things linking to or from the current page, and have a way of displaying in SVG. That would be cool.

Some work's been done to provide RDF metadata for individual wiki pages; see http://www.emacswiki.org/cgi-bin/community/DublinCoreForWiki.
Another project has been to add RDF "by hand" in a human-readable, convenient form, and create a complex web of useful implications. See http://www.srcf.ucam.org/~cjp39/Peri/MetadataSyntax and linked pages.
