Triple File Writer

KNIME Semantic Web Nodes version 4.3.0.v202011191625 by KNIME AG, Zurich, Switzerland

This node writes all triples from a given data table into a file. The Namespace of the subject, predicate, object URIs can be changed individually.
Supported file types are: *.ttl, *.rdf. *.rj, *.nt, *.trig, *.trix. For *.rdf files the path must not contain any whitespace nor be relative due to framework limitations.
