It's not about Leo. I tried to pick a subject line that made that clear but I guess that didn't work. From time to time I share things that I discover "out there" that are intriguing to me and I think might also interest some here. In this instance the fellow has a unique approach to storing and displaying information that I haven't encountered before. Leo also has a non-standard approach, so both being birds of uncommon feathers maybe there are some ideas for cross fertilization.
More specifically, the software that controls the website (
https://wiki.xxiivv.com/#oscean) is static, yet feels dynamic. The enitre text of the is just one page, with the media only fetched when those sections are navigated to. A slick architecture in my opinion, that puts me in mind of Leo. It's fed by flatfile data tables which are syntax free, using only whitespace, a kind of data markdown. It should be easy even for me to build a Leo parser, if my intrigue lasts long enough to go that way.
