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

Options

Subject

Column containing subjects of triples.

Predicate

Column containing predicates of triples.

Object

Column containing objects of triples.

Subject Namespace

If a namespace is given, the namespace of subject URIs will be changed.

Predicate Namespace

If a namespace is given, the namespace of predicate URIs will be changed.

Object Namespace

If a namespace is given, the namespace of object URIs will be changed.

Graph name

Column containing the names of the graphs in which the triplets should be stored.

Graph Namespace

If a namespace is given, the namespace of Graph URIs will be changed.

Global graph name

Graph name used for all input triples in the input table.

Subject Prepend

If chosen, the subject namespace will always be prepended.

Predicate Prepend

If chosen, the predicate namespace will always be prepended.

Object Prepend

If chosen, the object namespace will always be prepended.

Graph Prepend

If chosen, the graph namespace will always be prepended.
