The record

Purpose: RDF4J is a modular Java framework for parsing, storing, querying, and reasoning over RDF data.
SPARQL: The framework supports SPARQL 1.1 query and update and provides access to remote RDF repositories through the same API as local repositories.
RDF formats: RDF4J supports formats including RDF/XML, Turtle, N-Triples, N-Quads, JSON-LD, TriG, and TriX.
Storage: RDF4J includes a transactional in-memory store with optional disk persistence and a transactional Native Store that targets medium-sized datasets around 100 million triples.
Reasoning and validation: Extensions provide full-text search, RDFS inferencing, rule-based reasoning, SHACL and SPIN validation, and geospatial queries.
Integrations: The site lists compatible third-party stores and adapters including GraphDB, Halyard, Stardog, Amazon Neptune, Oracle RDF Graph Adapter, MarkLogic, and Virtuoso.
Developer tools: The RDF4J SDK bundles libraries, Server, Workbench, Console, and Javadoc API; the Workbench provides a web interface with a SPARQL editor.
Distribution: RDF4J can be retrieved as Maven artifacts or downloaded as an SDK zip or onejar.
Runtime requirement: The latest stable release, RDF4J 6.1.0, requires Java 25 or newer.
License: Eclipse RDF4J is distributed under the Eclipse Distribution License, version 1.0.
Limitations: The project describes its core databases as mainly intended for small to medium-sized datasets and says third-party stores may offer better scalability or extended features.
Security: The Eclipse project page links to the Eclipse Foundation vulnerability reporting channel.
Intended users: The site presents RDF4J as a framework for Java developers building applications with RDF, Linked Data, SPARQL endpoints, and Semantic Web data.
