ETL to RDF with Talend and AllegroGraph
This document provides steps for extracting data from a relational database and transforming it into RDF triples to load into an AllegroGraph RDF graph database using Talend ETL. The steps include connecting to the relational data source, collecting metadata on the tables and columns, creating a Talend job with a data source and mapper component, mapping the relational columns to RDF properties and classes, configuring the output, and testing the job to generate N-Triples, N-Quads, or N-Quads Extended triples for loading into the graph database.
