Just some thoughts on what I would include in a schema.org/Dataset jsonld package

dataset.jsonld

{
  "@context": "http://schema.org",
  "@type": "Dataset",
  "distribution": {
   "@type": "DataDownload",
   "url" :  "http://foo.org/datasets/set1.jsonld"
  }
  "spatial" : {
  "@type": "Place",
     "geo": {
       "@type": "GeoCoordinates",
       "latitude": "40.75",
       "longitude": "73.98"
     }
  },
  "author": {
     "@type": "JRSO",
     "name": "Joides Resolution Science Office",
     "description": "JRSO is the operating organization for the JR.  It is the final authority for DSDP, ODP, IODP and IODP (2014) data.",
     "url": "http://jrso.org"
  }
}
