  • Experimental support for RDF* and SPARQL*
  • Remote SHACL Validation reports in the Workbench
  • Query plan inspection through the new explain feature
  • Various significant performance and scalability improvements in the Native Store

For a complete overview, see all issues fixed in 3.2.0.

This release was made possible by contributions from Damyan Ognyanov, Pavel Mihaylov, Allesandro Bollini, Håvard Ottestad, Bart Hanssens, Andreas Schwarte, and Jeen Broekstra.

Upgrade notes

RDF4J 3.2.0 is binary compatible with older RDF4J releases. As an end-user, you can upgrade without any changes to your code.

For third party SAIL implementors, the following notes may be of interest:

To enable RDF* support in your SAIL implementation, you will need to ensure that your store accepts statements with a org.eclipse.rdf4j.model.Triple as either the subject or the object.

To additionally enable SPARQL* support, you will need to ensure that the org.eclipse.rdf4j.query.algebra.evaluation.TripleSource object supplied to the SPARQL EvaluationStrategy is extended to additionally implement org.eclipse.rdf4j.query.algebra.evaluation.RDFStarTripleSource. If your triplestore implements its own EvaluationStrategy for the RDF4J algebra model, you will need to extend it to evaluate the new org.eclipse.rdf4j.query.algebra.TripleRef and org.eclipse.rdf4j.query.algebra.ValueExprTripleRef nodes.

Please be advised that RDF* and SPARQL* support is currently experimental. We welcome your feedback on the current design and if you require any further input on how to best go about supporting RDF* and SPARQL*, we’d love to hear from you.


Eclipse RDF4J™ is a powerful Java framework for processing and handling RDF data. This includes creating, parsing, scalable storage, reasoning and querying with RDF and Linked Data. It offers an easy-to-use API that can be connected to all leading RDF database solutions. It allows you to connect with SPARQL endpoints and create applications that leverage the power of linked data and Semantic Web.
