Hello, and welcome to this awesome community.
I am very, and I really mean it – VERY interested in your project. I am an archivist by soul and a senior programmer by profession. 
Jokes aside, I love programming. But I quite like information archiving in general.
Lately I am working on bringing in a more contemporary sqlite support to Elixir. There’s a good library but it doesn’t support Ecto 3 which is the upgraded and better version of Ecto 2, which is a data mapper library, or an ORM if you will. Since Elixir is dynamically typed (still strongly typed but not checked at compile time) I’m also pondering adding a stricter typing to my library to make things a bit safer in general. Especially if you keep in mind that sqlite is weakly, or rather, value-typed, and not as strict as Postgres.
Where I am getting with this is that I very much would like to author a Wiki-like software in Elixir, backed by Ecto – which in combination with my other effort, will open it up for being backed by sqlite as well (not only by Postgres and MySQL which are the best supported DB backends for Ecto).
I happen to believe Wikis are way too huge and bloated software packages in general and I’m seeking to bring Elixir’s speed to this area (I mean, it’s not the speediest language but it’s definitely beating Ruby, Python and PHP, and sometimes JS). Fault tolerance and transparent parallelism, too. Elixir is also quite lightweight.
Between Elixir’s releases (self-contained packages) and sqlite (serverless DB) I think Wikis can be made very lean and mean. I’d love working on that.
