Thanks for the link, that's a great site (and they are using dokuwiki!) which can allow for searches for wikis that include
text based data support. There didn't seem to be any way to search for semantic features, do you know of any other wikis with such a feature that use text file data system like DokuWiki?
It seems like a semantic internal system and RDF output could be brought to DokuWiki through plugins, is anyone currently pursuing this?
