Graph Merger
Graph Merger
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.
Name | Description | Example |
---|---|---|
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/ |
Name | Type | Data Unit | Description | Required |
---|---|---|---|---|
input | input | RDFDataUnit | Input graphs which are to be merged | |
output | output | RDFDataUnit | RDF graph which contains all triples from the input graphs |
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.
