coming back to this old thread … I am working on an implementation generating schema.org markup from term data bases - still with the goal to represent the „translated_as“ relation between terms. The google validation tool gives me for the below input 

{ 
  "@context": "http://schema.org/",
  "@id": "http://example.com/my-term-data-base-entry-1",
  "type" : "schema:Thing",
 "schema:inLanguage": "ja",
 "schema:name": "ページ",
 "schema:sameAs": {
   "@id": "http://example.com/my-term-data-base-entry-2",
   "type" : "schema:Thing",
   "schema:inLanguage": "en",
   "schema:name": "page"
 } }

The attached error messages. How could I adapt the example? Or is this an issue with the tool?

Best,

Felix
