I've now got wibur in my svn repository, and have been fixing it. Currently the software isn't functional.
The tendency to not reuse is evident in force in wilbur. It has its own XML parser and HTTP client. Granted, these didn't exist as components in the lisp world when the project started, but that's hardly the case now.
My first task is still to pull out a triple store and the triple store API from wilbur. I really need to have them be independent components before I can turn cl-wiki into a semantic wiki. I'll get to the rdf parser in time, when it comes to importing ontologies into the semantic wiki.
(Or should importing existing ontologies be the first step? Hmmm....)
