What it does

SPARQL is a query language for RDF graphs.

About SPARQL, see http://www.w3.org/TR/rdf-sparql-query/

How to use

To use this tool a user first needs SPARQL query as an input.

For example:

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

Please input a SPARQL endpoint URL ( e.g. http://www.semantic-systems-biology.org/biogateway/endpoint ) and select the SPARQL query dataset.

And click the execute button.

The results can be shown on the middle pane by clicking the eye symbol on the history pane.

Note: SPARQL results has a header line (e.g. ?S ?V ?O). If you want to remove the header line, use the 'Text Manipulation / Remove beginning' tool, and remove a first line.

Output

SPARQL results as tabular format.

Example

If you specify example parameter, the results was:

?s      ?p      ?o
