> This means the same topic can be treated in completely different ways. For example geology.wiki/article/Mountain may be completely different different from poetry.wiki/article/Mountain.
Doesn't MediaWiki (and other common wikis) support this kind of thing already via the InterWiki-links system? You can set up a MediaWiki install such that [[geology:Mountain]] and [[poetry:Mountain]] go to the appropriate places. What does Ibis add that's not accounted for by this?
Besides, these days you also have https://www.wikidata.org/wiki/Q8502 - which includes links to the concept of "mountain" as represented in hundreds of sites. (You can use a browser-extension known as Entity-Explosion to make your browser aware of these links, giving you the ability to browse from any of the listed sites to any other with just a few clicks.)
