Abstract. Shipping policies allow for deciding whether a query should be exe-cuted at the server, the client or distributed among these two. Given the limita-tions of public SPARQL endpoints, selecting appropriate shipping plans is crucial for successful query executions without harming the endpoint performance. We present PLANET, a query plan visualizer for shipping strategies against a single SPARQL endpoint. We demonstrate the performance of the shipping policies fol-lowed by existing SPARQL query engines. Attendees will observe the effects of executing different shipping plans against a given endpoint. 1
