E.g., [["context/namerica","category/river"]]. Some terms are translated to all languages:

     {
       "categories": [
         "world",
         "namerica",
         "river"
       ],
       "id": "Yukon",
       "name-cs": "Yukon",
       "name-de": "Yukon River",
       "name-en": "Yukon",
       "name-es": "Yuk\u00f3n",
       "name-ru": "\u042e\u043a\u043e\u043d",
       "name-sk": "Yukon"
     },

, but others are only in some languages:

     {
       "categories": [
         "namerica",
         "river"
       ],
       "id": "Colorado",
       "name-cs": "Colorado",
       "name-en": "Colorado",
       "name-sk": "Colorado"
     },
