To a regular human being rather than a wikipedian, that might as well 
have been written in Klingon. :)

I suspect that trying to rely on wikidata/wikipedia for this link will 
fail for a different reason though - the things that we tag in OSM won't 
necessarily map 1 to 1 onto wikipedia pages. Sometimes an OSMer will 
want to indicate that a wider area than is indicated in 
GVP/wikipedia/wikidata, but much more often an OSMer will be tagging an 
individual volcano that might not match where a historical eruption took 
place (think Thera / Santorini, where a famous eruption left a big hole, 
now surrounded by numerous modern features).

It does make sense to use (and document) GVP's "active" definition in 
OSM, but there will be places in OSM where it's not a good fit, because 
what was there that erupted earlier in the last few thousand years isn't 
there now.
