Liking this very practical linkage.

Implementation question - would the url lists.schema.org/Country/Mexico

   1. Redirect to the relevant Wikidata page (
   2. Resolve to a Schema.org branded html page populated by data imported
   from Wikidata, with embedded schema.org that looks something like this:

   1. <script type="application/ld+json">
   2. {
   3.     "@context": "http://schema.org/",
   4.     “@type": "Country",
   5.     “name”: "Mexico",
   6.     “sameAs": "https://www.wikidata.org/wiki/Q96"
   7. }
