+# RDF4J-Spring Demo
+
+Small demo application for `rdf4j-spring`. 
+
+The purpose of `rdf4j-spring` is to use an RDF4J repository as the data backend of a spring or spring boot application.
+
+To run the demo, do 
+
+```$bash
+mvn spring-boot:run
+```
+
+The program writes to stdout and exits. The class [ArtDemoCli](src/main/java/org/eclipse/rdf4j/spring.demo/ArtDemoCli.java) is a good starting point for looking at the code.
