RDFCommander is a small tool to browse linked data (triples) using SPARQL Endpoints. It’s main goal is to be useful staying easy & intuitive as Total Commander. I wrote it to help me with debugging/discovering data from remote endpoints.

 

 

 

 

 

 

 

Connection

To connect you need to click: File –> Connect option or the “earth’ toolbar button. Then you need to select SPARQL endpoint (default is http://dbpedia.org/sparql) and initial Node URI. After successful connection you should see the data loaded into the main view. You can navigate using arrow keys (Up, Down). You can enter node using ENTER key. You can also navigate back with BACKSPACE or “Back” button.

View mode

Triples are presented in two modes: “Node as subject” or “Node as object”. That’s why there are only two parts of the triple visible at the same time (the third one is constant while navigating and there’s no need to show it in the list). The default view is “Node as subject” In this view the SPARQL endpoint is queried about all the triples with Subject set as the given node. You can change the view using “Swap view” command (or the toolbar button):

In “Node as object” view it loads all the triples with Object set as the given node (as shown below):
