Who would have thought creating an entire world would be so complicated and interconnected, but here we are. How do you keep track of it all?
I’ve used Obsidian for the Lonely Galaxy. I try to write up a topic there before posting it here or on the CBB. I also have a wiki that largely consists of polished (or not so polished) versions of those notes as well as forum posts I never bothered to document properly.
For conlanging I’ve been all over the place and back again. The grammar is easy enough. I just write in markdown. The lexicon is much harder because it needs to be searchable. I’ve tried Excel, Obsidian, TiddlyWiki, a JSON file, and currently a CSV file. I wish I could commit to one and stick with it but at this point I’m impressed I was able to preserve the lexicon through so many different formats.
Not sure if you meant @Treczoks setup specifically, but in general Mediawiki runs like any other web application. You can register a domain and open ports on your router to make it available remotely. Mediawiki is what Wikipedia runs on so the experience is more or less the same as editing a Wikipedia article. It has a lot of stuff that’s not strictly necessary for a single user environment like account management and email integration, but I can see it being useful if, like me, you like keeping track of how your ideas have evolved over time, since Mediawiki keeps track of article changes.
Other reasons I can see people picking it over Obsidian are ease of publication (just make it available as above) it’s FOSS, which Obsidian is not, and you can allow others to collaborate with you. Obsidian puts easy remote access, publication, and collaboration behind a paywall.
