Website (HTML/PHP) possible link to GraphDB?


In the course of a master's thesis I developed an ontology which I imported into Ontotext GraphDB. At this point I need to connect a website (HTML / PHP) with the ontology I imported into Ontotext GraphBD. My technical knowledge is not high so I wondered if it is possible to connect these two components and if yes how can I do it?

I have on one side a website and on the other an ontology in GraphDB. Now I need that in this website it is possible for example to do CRUD operations so that these operations are also done in the ontology that is in Ontotext GraphDB.

Example: Consult through my website all the individuals present in the ontology.

I in the Ontotext GraphDB workbench through the Sparql queries I get these operations, but I want to do it through the website that I'm doing in HTML, PHP and CSS.

Thanks for your attention.

Best regards


Solution

  • I think I solved my problem with this here.

    In general, you need to download Semsol's ARC2 library.

    Then you create the php file with a structure like this:

    <?php
      /* ARC2 static class inclusion */ 
      include_once('semsol/ARC2.php');  
    
      $dbpconfig = array(
      "remote_store_endpoint" => "http://dbpedia.org/sparql",
       );
    
      $store = ARC2::getRemoteStore($dbpconfig); 
    
      if ($errs = $store->getErrors()) {
         echo "<h1>getRemoteSotre error<h1>" ;
      }
    
      $query = '...';
    
      /* execute the query */
      $rows = $store->query($query, 'rows'); 
    
        if ($errs = $store->getErrors()) {
           echo "Query errors" ;
           print_r($errs);
        }
    
        /* display the results in an HTML table */
        echo "..." 
    
      ?>
    

    I thank everyone who tried to help me.
