Visualizing D2R rdf data using lodlive


I working on publishing linked data.

and I used D2R to publish data from relational database.

Now, I need to visualize these data, so I wanted to use lodlive script.

I got the project source code from https://github.com/withjam/ml-lodlive#dataset

I used this code to do that, but it didn't work!

<!DOCTYPE html>
<html style="width: 100%; height: 100%">
  <head>
    <title>LodLive Testing</title>
    <link rel="stylesheet" href="dist/ml-lodlive.all.css">
  </head>
  <body style="width: 100%; height: 100%">
    <div id="graph" style="width: 100%; height: 100%"></div>
    <script src="https://code.jquery.com/jquery-2.1.3.min.js"></script>
    <script src="dist/ml-lodlive.complete.js"></script>
    <script src="js/profile/profile.example.js"></script>
    <script>
        MyProfileObject.connection['http:'].endpoint = 'http://localhost:1111/sparql'; // to use the out-of-the-box MarkLogic SPARQL support
        MyProfileObject.connection['http:'].accepts = 'application/sparql-results+json'; // for regular XHR requests be sure to add this header to receive json response
        MyProfileObject.endpoints.jsonp = false; // depending on if you are using jsonp
        MyProfileObject.endpoints.all = ''; // and additional query params you wish to include in every request

      'use strict';
      jQuery('#graph').lodlive({ profile: MyProfileObject, firstUri: 'http://localhost:1111/data/organization/2', ignoreBnodes: true }); // 'http://dbpedia.org/resource/Philadelphia_Flyers'
    </script>
  </body>
</html>

Solution

  • I could do that using this HTML page:

    <!DOCTYPE html>
    <html style="width: 100%; height: 100%">
      <head>
        <title>LodLive Testing</title>
        <link rel="stylesheet" href="dist/ml-lodlive.all.css">
      </head>
    
      <body style="width: 100%; height: 100%">
        <div id="graph" style="width: 100%; height: 100%"></div>
        <script src="https://code.jquery.com/jquery-2.1.3.min.js"></script>
        <script src="dist/ml-lodlive.complete.js"></script>
        <script src="js/profile/profile.example.js"></script>
        <script>
          'use strict';
      jQuery('#graph').lodlive({ profile: ExampleProfile, firstUri:     'http://localhost:1111/data/organization/2', ignoreBnodes: true });
        </script>
      </body>
    </html>
    

    and created a profile file "profile.example.js" which declares that the endpoint is http://localhost:1111/sparql
