Language and RDF Types - Mutations

RDF N-Quad allows specifying a language for string values and an RDF type. Languages are written using @lang. For example

<0x01> <name> "Adelaide"@en .
<0x01> <name> "Аделаида"@ru .
<0x01> <name> "Adélaïde"@fr .
<0x01> <dgraph.type> "Person" .

See also how language strings are handled in queries.

RDF types are attached to literals with the standard ^^ separator. For example

<0x01> <age> "32"^^<xs:int> .
<0x01> <birthdate> "1985-06-08"^^<xs:dateTime> .

The supported RDF datatypes and the corresponding internal type in which the data is stored are as follows.

Storage Type Dgraph type <xs:string> string <xs:dateTime> dateTime <xs:date> datetime <xs:int> int <xs:integer> int <xs:boolean> bool <xs:double> float <xs:float> float <geo:geojson> geo <xs:password> password <> string <> dateTime <> dateTime <> int <> int <> int <> bool <> float <> float

See the section on RDF schema types to understand how RDF types affect mutations and storage.
