"long": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "-1.2345" } ,
"page": { "type": "uri" , "value": "http://www.example.com/a.html" }
} ,
{
"place": { "type": "literal" , "value": "Building B" } ,
"lat": { "datatype": "http://www.w3.org/2001/XMLSchema#float" …
