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.
Same, I’ve tried lots of different things and have never found anything that works perfectly for maintaining conlang vocab. I’ve tried a spreadsheet and database but I find them too awkward to work with easily. So the best way I’ve found is just using a formatted text file with markup (emacs+org-mode which has its own markup syntax that I like, and a lot of useful functionality for working with it–like metadata, searching, and exporting).
I think a wiki is probably the best format to organize all the world building stuff, but you still have to figure out for yourself how you want to organize it all and do all the linking–that’s my weak point. (I know there’s some specialized world-building software out there but it seems to all be online subscription stuff which is definitely not for me).
