12 **What it does**
|
|
|
13
|
|
|
14 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.

|
|
20 You could for example use this SPARQL Endpoint URL:
|
|
|
21
|
|
|
22 http://sparql.wikipathways.org/
|
|
|
23
|
|
|
24 and the following SPARQL query, which will select 25 sets of "subject", "predicate" and "object" out of the database, with no filtering at all::
|
|
|
25
|
|
|
26 SELECT ?s ?p ?o
|
|
|
27 WHERE { ?s ?p ?o }
|
|
|
28 LIMIT 10
|
|
|
29
|
|
|
30 This will generate a 3-column tabular output like this::
