Dialogue: 0,0:03:23.13,0:03:29.12,Default,,0000,0000,0000,,So, what happens is I want to use Wikidata\Nas the source of a lot of this stuff,

Dialogue: 0,0:03:58.02,0:04:01.10,Default,,0000,0000,0000,,And the reason I'm going to do that\Nis if I started with all of the rationale,

Dialogue: 0,0:04:06.18,0:04:12.12,Default,,0000,0000,0000,,So, my biggest suggestion, I guess,\Non the community side is,
