Re: [ = shortcut

oh... right, '=' is a shortcut for owl:sameAs! I totally forgot about that.

 From Henry's email, I thought that [= ID ... ] was a special kind of 
brackets, that allowed you to nest a description, but having ID as the 
subject of this description, rather than a fresh blank node.

This is a nice feature of JSON-LD (see example below) which I wish was 
available in the Turtle family of syntaxes.

{
   "@context": "https://schema.org/,

   "@id": "#pa",
   "@type": "Person",
   "affiliation": {
     "@id": "#w3",
     "@type": "Organization",
     "founder": {
       "@id": "#timbl",
       "@type": "Person
     }
   }
}
