**What it does**

The SPARQL import executes a SPARQL query against a SPARQL endpoint and returns the results in tabular format, with one column per variable in the SPARQL query.

-------

**Example**

You could for example use this SPARQL Endpoint URL:

http://sparql.wikipathways.org/

and the following SPARQL query, which will select 25 sets of "subject", "predicate" and "object" out of the database, with no filtering at all::

    SELECT ?s ?p ?o
    WHERE { ?s ?p ?o } 
    LIMIT 10

This will generate a 3-column tabular output like this::
