RDF4J overview

Eclipse RDF4J™ is a robust, open-source Java framework designed for handling Resource Description Framework (RDF) data. It empowers developers to create, parse, store, query, and reason with RDF and Linked Data, facilitating seamless integration with various RDF database solutions and SPARQL endpoints. This versatility makes it a cornerstone for applications leveraging Semantic Web technologies. The latest RDF4J update introduces enhanced JSON-LD 1.1 support, improving data handling to meet current standards. FedX now boasts better performance and expanded federation capabilities, while SHACL validation is refined with support for sh:closed and pairwise checks, ensuring stronger data integrity. Stability and performance improvements were made to the LMDB storage solution, alongside an upgraded MapDB for optimized database interactions. Additionally, more efficient query handling reduces RAM and heap space requirements by managing intermediary query results effectively.
