Two wikis are relatively IsolatedWikis to each other, if there is no single BidirectionalLink between them.
A Completely Isolated Wiki is a wiki that has neither BackLinks (incoming) , nor ForwardLinks (outgoing) from/to any other wiki.
It's kind of cosmic humour, that you can't point to IsolatedWikis: as soon as an observer of such a wiki, points to it from another wiki, this property gets lost;-)
One could object, that if wiki A has some links to wiki B, and wiki B has some links to wiki A, then both wikis couldn't be called IsolatedWikis to each other.
The term IsolatedWikis is deliberately used as a provocation. We have to find a better one ... Perhaps the wiki relations between wiki A,B could be classified as :
- UnconnectedWikis
- WeaklyConnectedWikis of type (m,n) with m links from A to B and n links from B to A and no BidirectionalLink
- StronglyConnectedWikis of type n with n BidirectionalLink''s between A and B
Note:
The author thinks, that the use of BidirectionalLinks or at least ReciprocalLinks could help to effectively defend against WikiSpam: each wiki link, that comes from an external wiki with no backlink there (with verifiable WikiPrefix syntax) could be eliminated easily, even automatically. I bet, this would be a strong motivator for WikiWeaving ;-)
The same holds for Website owners. If they leave a link to their website in this wiki, then only a visible and language compatible backlink on their referred page (with useful context) motivates the wiki, not to eliminate the foreign link.
