The NPCs that have their unique walking and standing animations seems to have been replicated too. See here: https://osrs.world/?cx=2956.96&cy=6&cz=3363.12&p=-151&y=2047&v=1 https://osrs.world/?cx=2956.96&cy=6&cz=3363.12&p=-151&y=2047... . OSRS wiki supports lookup by NPC IDs: https://oldschool.runescape.wiki/w/Special:Lookup?type=npc&id=2793 https://oldschool.runescape.wiki/w/Special:Lookup?type=npc&i... . So that itself isn't too complicated. I think the dataset they're using is https://archive.openrs2.org/ https://archive.openrs2.org/ . It looks like NPC data might be a part of that. This version has the wrong NPC mappings, and also missing object data: https://osrs.world/?cx=3262.58&cy=8.22&cz=3265.93&p=-244&y=1862&cache=osrs-16_2013-07-05&v=1 https://osrs.world/?cx=3262.58&cy=8.22&cz=3265.93&p=-244&y=1... Older Runescape 2 (pre-OSRS) caches have objects but no NPCs.
