To load Resource Description Framework (RDF) data, you can use one of the following standard formats as specified by the World Wide Web Consortium (W3C):


All files must be encoded in UTF-8 format.

For N-Quads and N-triples data that includes Unicode characters, \uxxxxx escape sequences are supported. However, Neptune does not support normalization. If a value is present that requires normalization, it will not match byte-to-byte during querying. For more information about normalization, see the Normalization page on
