Field Details
-
VERIFY_DATATYPE_VALUES
Boolean setting for parser to determine whether values for recognised datatypes are to be verified.Verification is performed using registered DatatypeHandlers.
Defaults to false.
Can be overridden by setting system property
org.eclipse.rdf4j.rio.verify_datatype_values
. -
FAIL_ON_UNKNOWN_DATATYPES
Boolean setting for parser to determine whether to fail parsing if datatypes are not recognised.Datatypes are recognised based on matching one of the registered
DatatypeHandler
s.Defaults to false.
Can be overridden by setting system property
org.eclipse.rdf4j.rio.fail_on_unknown_datatypes
. -
NORMALIZE_DATATYPE_VALUES
Boolean setting for parser to determine whether recognised datatypes need to have their values be normalized.Normalization is performed using registered DatatypeHandlers.
Defaults to false.
Can be overridden by setting system property
org.eclipse.rdf4j.rio.normalize_datatype_values
. -
DATATYPE_HANDLERS
Setting used to specify whichDatatypeHandler
implementations are to be used for a given parser configuration.Defaults to an XMLSchema DatatypeHandler implementation based on
DatatypeHandler.XMLSCHEMA
and an RDF DatatypeHandler implementation based onDatatypeHandler.RDFDATATYPES
. -
FAIL_ON_UNKNOWN_LANGUAGES
Boolean setting for parser to determine whether to fail parsing if languages are not recognized.Languages are recognized based on matching one of the registered
LanguageHandler
s.Defaults to false.
Can be overridden by setting system property
org.eclipse.rdf4j.rio.fail_on_unknown_languages
. -
VERIFY_LANGUAGE_TAGS
Boolean setting for parser to determine whether languages are to be verified based on a given set of definitions for valid languages.Verification is performed using registered
LanguageHandler
s.Defaults to true.
Can be overridden by setting system property
org.eclipse.rdf4j.rio.verify_language_tags
. -
NORMALIZE_LANGUAGE_TAGS
Boolean setting for parser to determine whether languages need to be normalized.Normalization is performed using registered
LanguageHandler
s.Defaults to false.
Can be overridden by setting system property
org.eclipse.rdf4j.rio.normalize_language_tags
. -
LANGUAGE_HANDLERS
Setting used to specify whichLanguageHandler
implementations are to be used for a given parser configuration.Defaults to an BCP47 LanguageHandler implementation based on
LanguageHandler.BCP47
. -
VERIFY_RELATIVE_URIS
Boolean setting for parser to determine whether relative URIs are verified.Defaults to true..
Can be overridden by setting system property
org.eclipse.rdf4j.rio.verify_relative_uris
. -
VERIFY_URI_SYNTAX
Boolean setting for parser to determine if URIs should be verified to contain only legal characters.Defaults to
true
. If set tofalse
, the parser will report syntactically illegal URIs to theRDFHandler
.Can be overridden by setting system property
org.eclipse.rdf4j.rio.verify_uri_syntax
. -
PRESERVE_BNODE_IDS
Boolean setting for parser to determine whether parser should attempt to preserve identifiers for blank nodes. If the blank node did not have an identifier in the document a new identifier will be generated for it.Defaults to false.
Can be overridden by setting system property
org.eclipse.rdf4j.rio.preserve_bnode_ids
. -
SKOLEMIZE_ORIGIN
Scheme and authority of new mint Skolem IRIs that should replace Blank Nodes. For example a value of "http://example.com" might cause a blank node to be replaced with an IRI of "http://example.com/.well-known/genid/d26a2d0e98334696f4ad70a677abc1f6"Defaults to null (disabled).
Can be overridden by setting system property
org.eclipse.rdf4j.rio.skolem_origin
. -
LARGE_LITERALS_HANDLING
Boolean setting for parser to determine whether parser should preserve, truncate, drop, or otherwise manipulate statements that contain long literals. The maximum length of literals if this setting is set to truncate or drop is configured usingLARGE_LITERALS_LIMIT
.Defaults to
LargeLiteralHandling.PRESERVE
. -
LARGE_LITERALS_LIMIT
IfLARGE_LITERALS_HANDLING
is set toLargeLiteralHandling.PRESERVE
, which it is by default, then the value of this setting is not used.If
LARGE_LITERALS_HANDLING
is set toLargeLiteralHandling.DROP
, then the value of this setting corresponds to the maximum number of bytes for a literal before the statement it is a part of is dropped silently by the parser.If
LARGE_LITERALS_HANDLING
is set toLargeLiteralHandling.TRUNCATE
, then the value of this setting corresponds to the maximum number of bytes for a literal before the value is truncated.Defaults to 1048576 bytes, which is equivalent to 1 megabyte.
Can be overridden by setting system property
org.eclipse.rdf4j.rio.large_literals_limit
. -
NAMESPACES
Setting to provide a collection of
Namespace
objects which will be used when parsing RDF as the basis for the default set of namespaces of the document.Namespaces specified within the RDF document being parsed will override these defaults
Defaults to
invalid reference
Namespaces.DEFAULT_RDF4J
-
PROCESS_ENCODED_RDF_STAR
Boolean setting for parser to determine whether it should process RDF-star triples encoded as RDF-compatible special IRIs back to RDF-star values. These IRIs start with urn:rdf4j:triple: followed by the base64-encoding of the N-Triples serialization of the RDF-star triple value.Parsers that support RDF-star natively will honour this setting too.
Defaults to true.
Can be overridden by setting system property
org.eclipse.rdf4j.rio.process_encoded_rdf_star
