Triple File Reader

StreamableKNIME Semantic Web Nodes version 4.4.0.v202104131408 by KNIME AG, Zurich, Switzerland

This node reads triples stored in a file into a Data Table. It supports files such as *.ttl, *.rdf. *.rj, *.nt, *.trig, *.trix. Please check Jena Documentation for further information.

The N-Triples format for the query result is necessary to be kept if you want to insert the triples in an endstore. This is especially imporant for (typed) literals. If the N-Triples format is not preserved type information will get lost (a String representation of the literal is returned). For URIs the angled brackets are not preserved, which are necessary for insertion. Here is an example showing triples with and without format preservation:
