OPAL batch

This component reads RDF files and applies the following OPAL components:

How to use

  • Download the latest release.
  • Create a copy of the default.properties file and edit the copy.
    At least, set io.input and io.outputDirectory.
  • Finally, run it by java -jar opal-batch.jar default.properties.

Get data to process

Data should be in a RDF serialization format and using the Data Catalog Vocabulary (DCAT) vocabulary.

You can find ready-to go input data at the Hobbitdata Server. Data from open data portals is available in the directories OPAL/processed_datasets and OPAL/SourceGraphs.
