SPARQL Interpreter for Apache Zeppelin

Overview

SPARQL is an RDF query language able to retrieve and manipulate data stored in Resource Description Framework (RDF) format. Apache Zeppelin for now only supports Apache Jena to query SPARQL-Endpoints.

To query your endpoint configure it in the Interpreter-Settings and use the %sparql interpreter. Then write your query in the paragraph. If you want the prefixes to replace the URI's, set the replaceURIs setting.

Configuration

Name Default Value Description
sparql.engine jena The sparql engine to use for the queries
sparql.endpoint http://dbpedia.org/sparql Complete URL of the endpoint
sparql.replaceURIs true Replace the URIs in the result with the prefixes
sparql.removeDatatypes true Remove the datatypes from Literals so Zeppelin can use the values
