What it is

Apache Jena Fuseki is a SPARQL server that can run independently or as part of an application. It provides SPARQL 1.1 query and update protocols and the SPARQL Graph Store protocol. Fuseki integrates with TDB for transactional persistent storage and includes Jena text query. It can run as a standalone server, an operating-system service, an embedded component, or a web application in Apache Tomcat or Jetty. The project offers a plain server without a UI, and distributions include a ZIP with server and UI, Maven artifacts, and a WAR file. A project kit can build Docker or Docker Compose containers; databases need mounted volumes to survive container removal. The web application uses Apache Shiro, with access control at server, dataset, endpoint, and graph levels. Graph-level controls currently apply only to read-only datasets. By default, administrative functions are limited to localhost, while SPARQL endpoints are open. Fuseki is free, self-hosted software under Apache License 2.0.
