        <h2>Query the Linked-Data and let its values Sparkle (aka SPARQL)</h2>

        <p>
          Using this page you can query the linked-data in the
          Greenstone3 triplestore graph using
          <a href="https://en.wikipedia.org/wiki/SPARQL">SPARQL</a>
          query syntax.  The default query provided in the text
          box below is effectively issuing a query that returns
          everything stored (a bit like matching with the wildcard
          '*' that some text-based search systems have), limited
          to show just the first 500 entries that matched.
        </p>
        
        <p>
          Use the default query to get a feel for the data that is
          stored.  Feel free to experiment with the syntax to vary
          what is returned.  For example, to view other "slices"
          of the rows of data returned, change the values of
          OFFSET and LIMIT.  OFFSET controls how many result rows
          are skipped over before rows are selected.  LIMIT
          controls how many rows are then taken.
          
        </p>

        <div id="sparql-show-more" class="showmore">
          <p>
        Alternatively, you might be interested in experimenting
        with forms of access to the triplestore through the more powerful, but complex:
        <ul>
          <li>
            <!-- endpoint -->
            <a target="_blank" href="//{$sparqlEndpointHostAndOptPort}{$sparqlEndpointPrefix3}/dataset.html?tab=query&amp;ds=/greenstone">Fuseki interface</a>

          </li>
        </ul>
          </p>
          <p>
        Or else export the entire triplestore to work on it with whichever Linked Data tools are your preference:
        <ul>
          <li>
            <!-- endpoint -->
            <a href="//{$sparqlEndpointHostAndOptPort}{$sparqlEndpointPrefix3}/greenstone/data" download="greenstone3-{$collNameChecked}-lod.trig">Full Export in TriG Syntax</a>
