Apologies if the answer to this is here already but I've done a search on this and nothing comes up when I search on Interwiki.
May I ask, does the Vaultwiki software support Interwiki so that like this software (Dokuwiki) at the link below which claims to have "customizable interwiki links" you can link content in one wiki to another?
https://www.dokuwiki.org/features
The features comparison says that the Dokuwiki software provides "BBCode Support" as a plug in so I'd be surprised if you can't link content between e.g. Vaultwiki and Dokuwiki.
