Ubik Wiki
UbikWiki (pronounced as close to "Ubiquity" as can be managed) is a new breed of WikiEngine, featuring:
- TeX-like formatting syntax
- Valid HTML 4.0 Transitional pages
- Pseudonyms (one page with multiple names)
- Extensible link syntax
- Transclusions
- Namespaces (well, something very similar)
- Trails
The thing that Ubik is trying to showcase is not any of these (directly), it's a more fundamental design change called SetFacetWiki - a (fairly distant) variant of the scheme proposed in WikiMultipleDefinitions. SetFacetWiki is an alternative to SubPages and SectionedPages, and provides a nice foundation for most of the features listed above
UbikWiki is no longer up and has been deprecated by its owner ChrisPurcell (See Page on SisterSite)
