 - integer value for several id in the original JSON: not accepted by JSLD Playground nor by Titanium
-- issue in Titanium [triples with aliased @id and @base are missing at root level](https://github.com/filip26/titanium-json-ld/issues/61)
+
+An alternative is adding new JSON-LD `@id` keys in the current JSON, like this in /observations instance :
+
+  `"@id" : "5414154" ,`
+
+Also it will help to add this new JSON-LD `@id` key in /observations instances :
+  `"@type": [ "nature:Observation", "dwc:HumanOrservation" , "dwc:Occurrence" ] ,
+
+And this new JSON-LD `@id` key in /users instances :
+
+  `"@type": [ "foaf:Person", "schema:Person" ] ,
