Any chance to release this as an open source? For example, people would like to have installed in their servers and use it for their own things. I think it would be useful for fandom. For example, the Star Wars DB or Lord of the Rings Db :-)
Check, for example, Wikia, which contains Wikipedia for TV Shows which are more complete than Wikipedia.
If you're worried about competition, release under AGPL.
Similarly for the data, to the extent restricted by copyright and such, release under CC0 (same as Wikidata). Or if you want to be onerous, ODbL.
Some neat ideas in the project in any case, good luck!
