Triple File Writer

KNIME Semantic Web Nodes version 4.2.0.v201912131004 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.

In order to prepend namespaces it is necessary to choose Prepend in the settings dialogue.

Functionality is provided using the Apache Jena Framework
