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

This node inserts Semantic Web triples in an endpoint. A triple consists of subject (URI), predicate (URI), object (URI, literal). URIs have to be encapsulated in angled brackets (<, >), literals can be in their lexical form or in combination with their data type. Graph names do not need to be placed in angled brackets when entering them in the dialogue, or when they are given in table. Setting subject, predicate and object is mandatory.

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

The usage of option "Graph name" and "Global graph name":

Graph name Graph name cell Global Graph name Used
selected not missing don't care Graph name cell
selected missing not empty Global Graph name
selected missing empty Default graph
not selected don't care not empty Global graph name
not selected don't care empty Default graph
Attention: It depends on connected Semantic Web endpoint whether using default graph is permitted.

Functionality is provided using the Apache Jena Framework
