    Loads N-Quads data from a file or directory into a DataSet.

    Loads N-Quads data from a file or directory into a DataSet. The path can also contain multiple paths and even wildcards, e.g. "/my/dir1,/my/paths/part-00[0-5]*,/another/dir,/a/specific/file"

    Handling of errors

    By default, it stops once a parse error occurs, i.e. a org.apache.jena.riot.RiotException will be thrown generated by the underlying parser.

    The following options exist:

    • STOP the whole data loading process will be stopped and a org.apache.jena.net.sansa_stack.rdf.spark.riot.RiotException will be thrown
    • SKIP the line will be skipped but the data loading process will continue, an error message will be logged

    Handling of warnings

    If the additional checking of RDF terms is enabled, warnings during parsing can occur. For example, a wrong lexical form of a literal w.r.t. to its datatype will lead to a warning.

    The following can be done with those warnings:

    • IGNORE the warning will just be logged to the configured logger
    • STOP similar to the error handling mode, the whole data loading process will be stopped and a org.apache.jena.riot.RiotException will be thrown
    • SKIP similar to the error handling mode, the line will be skipped but the data loading process will continue

    Checking of RDF terms

    Set whether to perform checking of NTriples - defaults to no checking.

    Checking adds warnings over and above basic syntax errors. This can also be used to turn warnings into exceptions if the option stopOnWarnings is set to STOP or SKIP.

    • IRIs - whether IRIs confirm to all the rules of the IRI scheme
    • Literals: whether the lexical form conforms to the rules for the datatype.
    • Quads: check slots have a valid kind of RDF term (parsers usually make this a syntax error anyway).

    See also the optional errorLog argument to control the output. The default is to log.
