Field Summary

Fields

Modifier and Type	Field and Description
static RioSetting<Boolean>	COMPACT_ARRAYS If set to true, the JSON-LD processor replaces arrays with just one element with that element during compaction.
static RioSetting<com.github.jsonldjava.core.DocumentLoader>	DOCUMENT_LOADER If specified, it is used to retrieve remote documents and contexts; otherwise the processor's built-in loader is used.
static RioSetting<Boolean>	HIERARCHICAL_VIEW If set to true, the JSON-LD processor will try to represent the JSON-LD object in a hierarchical view.
static RioSetting<JSONLDMode>	JSONLD_MODE The JSONLDMode that the writer will use to reorganise the JSONLD document after it is created.
static RioSetting<Boolean>	OPTIMIZE If set to true, the JSON-LD processor is allowed to optimize the output of the Compaction algorithm to produce even compacter representations.
static RioSetting<Boolean>	PRODUCE_GENERALIZED_RDF If set to true, the JSON-LD processor may emit blank nodes for triple predicates, otherwise they will be omitted.
static RioSetting<Boolean>	USE_NATIVE_TYPES If set to true, the JSON-LD processor will try to convert typed values to JSON native types instead of using the expanded object form when converting from RDF.
static RioSetting<Boolean>	USE_RDF_TYPE If set to true, the JSON-LD processor will use the expanded rdf:type IRI as the property instead of @type when converting from RDF.

Field Detail

COMPACT_ARRAYS

public static final RioSetting<Boolean> COMPACT_ARRAYS

If set to true, the JSON-LD processor replaces arrays with just one element with that element during compaction. If set to false, all arrays will remain arrays even if they have just one element.

Defaults to true.

Can be overridden by setting system property org.eclipse.rdf4j.rio.jsonld.compact_arrays.

DOCUMENT_LOADER

public static final RioSetting<com.github.jsonldjava.core.DocumentLoader> DOCUMENT_LOADER

If specified, it is used to retrieve remote documents and contexts; otherwise the processor's built-in loader is used.

OPTIMIZE

public static final RioSetting<Boolean> OPTIMIZE

If set to true, the JSON-LD processor is allowed to optimize the output of the Compaction algorithm to produce even compacter representations.

Defaults to false.

Can be overridden by setting system property org.eclipse.rdf4j.rio.jsonld.optimize.

PRODUCE_GENERALIZED_RDF

public static final RioSetting<Boolean> PRODUCE_GENERALIZED_RDF

If set to true, the JSON-LD processor may emit blank nodes for triple predicates, otherwise they will be omitted. Note: the use of blank node identifiers to label properties is obsolete, and may be removed in a future version of JSON-LD,

Defaults to false.

Can be overridden by setting system property org.eclipse.rdf4j.rio.jsonld.produce_generalized_rdf.

USE_NATIVE_TYPES

public static final RioSetting<Boolean> USE_NATIVE_TYPES

If set to true, the JSON-LD processor will try to convert typed values to JSON native types instead of using the expanded object form when converting from RDF. xsd:boolean values will be converted to true or false. xsd:integer and xsd:double values will be converted to JSON numbers.

Defaults to false for RDF compatibility.

Can be overridden by setting system property org.eclipse.rdf4j.rio.jsonld.use_native_types.

USE_RDF_TYPE

public static final RioSetting<Boolean> USE_RDF_TYPE

If set to true, the JSON-LD processor will use the expanded rdf:type IRI as the property instead of @type when converting from RDF.

Defaults to false.

Can be overridden by setting system property org.eclipse.rdf4j.rio.jsonld.use_rdf_type.

JSONLD_MODE

public static final RioSetting<JSONLDMode> JSONLD_MODE

The JSONLDMode that the writer will use to reorganise the JSONLD document after it is created.

Defaults to JSONLDMode.EXPAND to provide maximum RDF compatibility.

HIERARCHICAL_VIEW

public static final RioSetting<Boolean> HIERARCHICAL_VIEW

If set to true, the JSON-LD processor will try to represent the JSON-LD object in a hierarchical view.

Default to false

Can be overridden by setting system property org.eclipse.rdf4j.rio.jsonld.hierarchical_view.
