OWNERSHIP: servers[] names https://impossiblemetals.com/wp-json/tribe/events/v1/ — the document is generated and served by Impossible Metals'' own host and describes Impossible Metals'' own event, venue and organizer records. info.contact is absent here; the sibling tec/v1 document names The Events Calendar (StellarWP) because the WordPress plugin generates the description, exactly as a self-hosted/templated server does.'
