Apache Jena - Fuseki : Main Server

Fuseki main is a packaging of Fuseki as a triple store without a UI for administration.

Fuseki can be run in the background by an application as an embedded server. The application can safely work with the dataset directly from java while having Fuseki provide SPARQL access over HTTP. An embedded server is useful for adding functionality around a triple store and also for development and testing.

The main server does not depend on any files on disk (other than for databases provided by the application), and does not provide the Fuseki UI or admins functions to create dataset via HTTP.

Running as a configured deployment or development server

The artifact org.apache.jena:jena-fuseki-server is a packaging of the “main” server that runs from the command line. Unlike the UI Fuseki server, it is only configured from the command line and has no persistent work area on-disk.

java -jar jena-fuseki-server-$VER.jar --help

The arguments are the same as the full UI server command line program. There are no special environment variables.

The entry point is org.apache.jena.fuseki.main.cmds.FusekiMainCmd so the server can also be run as:

java -cp jena-fuseki-server-$VER.jar:...OtherJars... \
    org.apache.jena.fuseki.main.cmds.FusekiMainCmd ARGS

Docker

A kit to build a container with docker or docker compose

https://repo1.maven.org/maven2/org/apache/jena/jena-fuseki-docker/

Note: take care that databases are on mounted volumes if they are to persist after the container is removed.

See the Fuseki docker tools page for details.

Running as an embedded server

Fuseki can be run from inside an Java application to provide SPARQL services to application data. The application can continue to access and update the datasets served by the server.

To build and start the server:

Dataset ds = ...
FusekiServer server = FusekiServer.create()
  .add("/dataset", ds)
  .build() ;
server.start() ;

See Fuseki embedded documentation for details and examples.
