Graph Merger (uv-t-rdfGraphMerger):
This DPU merges RDF input graphs into a single new RDF output graph. This means that all triples from the input graphs are put into a single new output graph.
|Output graph name||Name (URI) of the graph on output. This name is used in other DPUs, e.g. when loading the RDF graph to an external triple store as a destination graph name.||http://schema.org/|
Inputs and Outputs
|input||input||RDFDataUnit||Input graphs which are to be merged|
|output||output||RDFDataUnit||RDF graph which contains all triples from the input graphs|
Load RDF Data From Two Different Sources and Merge Them Into One Graph, Then Perform a SPARQL Construct on Them
The following image shows a fragment of a pipeline which
- downloads an Excel file and converts it to RDF;
- makes a HTTP Request to a triple store and gets RDF data.
It then proceeds to merge both input graphs to one single output graph. This graph is then processed in a SPARQL Construct query. The configuration of the GraphMerger DPU is shown in the image below.
