era-data-mappings

RML mappings to generate the ERA Knowledge Graph. The mappings are defined using the YARRRML syntax.

Requirements

• Node.js
• Java JRE

Execute mappings

The mappings can be executed using the map-turtle.sh or map-ntriples.sh scripts. These scripts will run the mapping process for all the YARRRML files present in the mappings/ folder. The resulting Linked Data files will be stored in the knowledge-graph/ folder.

./map-turtle.sh
