The Data2RDF configuration

The configuration of the package is crucial for the correct parsing and transformation of the data into RDF. The configuration is done via a dictionary which is passed to the Data2RDF constructor. The configuration is used to define the base IRI for the individuals, the QUDT unit and quantity kinds, the separator used for the IRI, the encoding used for parsing etc. Below you can find a table with the keys and their corresponding data types, descriptions and default values.

Key	Data Type	Description	Default Value	Required
qudt_units	AnyUrl	URI to QUDT Unit ontology for unit conversion	http://qudt.org/2.1/vocab/unit	No
qudt_quantity_kinds	AnyUrl	URI to QUDT quantity kind ontology for unit conversion	http://qudt.org/vocab/quantitykind/	No
base_iri	AnyUrl	Base IRI for individuals	https://www.example.org	No
prefix_name	str	Prefix used referencing the base_iri in the context of the graph	fileid	No
separator	str	Separator between base IRI and suffix	/	No
encoding	str	Encoding used while parsing	utf-8	No
data_download_uri	AnyUrl	General base iri for downloading the dataframe after uploading	https://www.example.org/download	No
graph_identifier	Optional[str, AnyUrl]	Identifier of the graph to be produced	None	No
namespace_placeholder	Union[str, AnyUrl]	Placeholder of the extra triples to be replaced with the base_iri during the pipeline run	http://abox-namespace-placeholder.org/	No
remove_from_unit	List[str]	Characters which should be removed from the input value for the unit	[“[”, “]”, ‘”’, “ “]	No
mapping_csv_separator	str	When the mapping file is a csv, the separator to be used for parsing	;	No
remove_from_datafile	List[str]	In plain text parsers, e.g. the CSV-parser, there might be the need to remove certain characters when parsing	[‘”’, “\r”, “\n”]	No
suppress_file_description	bool	In ABox mode, the pipeline is producing an additional subgraph graph for describing the data file in its structure, mime type, etc. This will be suppressed if enabled.	False	No
exclude_ontology_file	bool	In TBox mode, exclude the title of the ontology in the graph.	False	No
