Some highlights:

  • new static factory methods for easier creation of IRIs, Literals, and blank nodes;
  • new modules rdf4j-model-api and rdf4j-model-vocabulary for leaner dependency footprint in lightweight projects;
  • support for the java.time API;
  • custom character encoding in writers for RDF or query results;
  • improved performance of remote SPARQL query result pass-through;
  • improved performance of sorting and ordering operations in SPARQL query processing;
  • support for Java 15;

Upgrade notes

RDF4J 3.5.0 is binary compatible with older RDF4J releases.

Nevertheless, when upgrading existing projects, the following should be taken into account:

Maven dependencies

The rdf4j-model module has been split into three separate modules: rdf4j-model-api, rdf4j-model-vocabulary, and rdf4j-model.

If your project does not use transitive dependency resolution for the RDF4J modules, you will need to add two new additional dependencies to your project configuration:

<dependency>
    <groupId>org.eclipse.rdf4j</groupId>
    <artifactId>rdf4j-model-api</artifactId>
    <version>3.5.0</version>
</dependency>
<dependency>
    <groupId>org.eclipse.rdf4j</groupId>
    <artifactId>rdf4j-model-vocabulary</artifactId>
    <version>3.5.0</version>
</dependency>
