This node updates triples in a Semantic Web endpoint based on the triples from the input table. It is mandatory to choose a column for "Update value".
In order to prepend namespaces it is necessary to choose Prepend in the settings dialogue.
Additionally, you have to select further columns for subject, predicate and object. If all triple columns are selected (i.e. subject, predicate, object), the table is read out row-wise. It is possible to leave out subject, predicate, object cells empty; but at least one of these cells has to be non-empty.
Always the least significant element is updated with the entry in column "Update value". For instance, the following inputs are permitted:
If only one or two of the triple columns are picked, only these selected columns will be read-out. For instance, if you desire to update an object in a specific triple like SubjectPredicateObjectUpdate valueWhich element is updated?PeterCountryGermanyAustriaObject but only subject and predicate column are chosen, the update query will be interpreted as SubjectPredicateObjectUpdate valueWhich element is updated?PeterCountryAustriaPredicate This may yield wrong results.
