RDF_PROTO

public static final RDFFormat RDF_PROTO

RDF Protobuf output. This format is faithful representation of RDF written and it is suitable for database dumps. It does not encode numeric literals as values (see RDF_PROTO_VALUES).

See Also:

• RDF_PROTO_VALUES

RDF_PROTO_VALUES

public static final RDFFormat RDF_PROTO_VALUES

A variant of an an RDFFormat that uses value encoding (e.g. integers, doubles, decimals as binary). This does not preserve exact representation (+001 is the same value as 1, +1 and 001) which may matter for database dumps. It looses datatype for derived types (xsd:long, xsd:int, xsd:short and xsd:byte become xsd:integer). For large volumes of numeric data, it may provide a significant reduction in size in combination with using prefixes for subjects and predicates.

See Also:

• RDF_PROTO

RDF_THRIFT

public static final RDFFormat RDF_THRIFT

RDF Thrift output. This format is faithful representation of RDF written and it is suitable for database dumps. It does not encode numeric literals as values (see RDF_THRIFT_VALUES).

See Also:

• RDF_THRIFT_VALUES

RDF_THRIFT_VALUES

public static final RDFFormat RDF_THRIFT_VALUES

A variant of an an RDFFormat that uses value encoding (e.g. integers, doubles, decimals as binary). This does not preserve exact representation (+001 is the same value as 1, +1 and 001) which may matter for database dumps. It looses datatype for derived types (xsd:long, xsd:int, xsd:short and xsd:byte become xsd:integer).

RDFNULL

public static final RDFFormat RDFNULL

The "null" output format (a sink that prints nothing, usually quite efficiently)

RDFRAW

public static final RDFFormat RDFRAW

Stream-only output format for development - flushes every line.
