Description

Jena, a Java RDF API and toolkit is a Java framework to construct Semantic Web Applications. It provides a programmatic environment for RDF, RDFS and OWL, SPARQL, GRDDL, and includes a rule-based inference engine.

TDB provides a lightweight, scalable non-transactional storage and SPARQL query layer.

SDB is a SPARQL database subsystem for Jena. It provides for large scale storage and query of RDF data sets using conventional SQL databases. The database tools for load balancing, security, clustering, backup and administration can all be used to manage the installation. It offers an RDF Triple Store facility with SPARQL interface on top of other database systems.

Joseki is a SPARQL server based on Jena.
