SPARQL linker chunked
Transformer, allows the user to transform chunked RDF data in combination with a smaller reference dataset using a CONSTRUCT query. This means that based on the input data and the reference data, output data will be generated using this query, preserving the data chunking.

The SPARQL linker chunked component queries input and reference data combined, using a SPARQL CONSTRUCT query, producing new data on the output. This component can be used to, e.g. link bigger chunked data coming from, e.g. Tabular chunked, with a codelist in the reference dataset, preserving the data chunks for further chunked processing. It can be configured at runtime using RDF configuration, which can be generated by another component. Chunked RDF data is produced e.g. by Files to RDF chunked, SPARQL endpoint chunked or Tabular chunked.
Runtime configuration
Below you can see sample runtime configuration for the component. Note that RDF blank nodes are not allowed in runtime configurations.
