RDF4J 5.0.0 Milestone 2

Tue, Oct 17, 2023

Milestone number 2 of the upcoming 5.0.0 release of RDF4J is now available for download.

Notable changes since the previous milestone build:

  • We have switched to the new CONFIG vocabulary. If you ware interacting with the config files directly then take care to use the new vocabulary and if need be use the Configuration class to help with handling use cases where the new and old config vocabularies are mixed.
  • The refactoring and optimizations of the various iterations is nearing completion and there should be very few iterations that are still marked as deprecated.
  • More deprecated code has been removed, if you find that you were depending on deprecated code that is now removed then please let us know.

This milestone build is not yet feature-complete, but we are putting it out to receive early feedback on all the improvements we have put in.


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.
