Visualization tool for simplifying access to Linked Data.

The goal of this application is to provide users with a visualization tool which would allow them to query basic data without the need to learn SPARQL or understand RDF.

Consider the following example data schema described in an example .ttl file containing a description of Nobel Prize data schema.

To query for Nobel prizes and their laureates, the users would first have to have an understanding of what the data schema represents and would have to know how to write the following SPARQL query:

PREFIX nobel: <http://data.nobelprize.org/terms/>
SELECT DISTINCT ?NobelPrize ?Laureate WHERE {
  ?NobelPrize a nobel:NobelPrize.
  ?NobelPrize nobel:laureate ?Laureate.
  ?Laureate a nobel:Laureate.
} 

With the application, the data schema in question would be visualized as follows:

The user can immediately see the connections between the entities and can create selections to query for the data they are interested in.

Querying for the Nobel prizes and their laureates would then be as easy as doing the following, which would in turn create the query mentioned above:

The user can then just run the query using the button to produce the following results:

Additional examples providing a closer look at the functionality of the application can be found in the PDF Documentation under 5.1.5 Examples.
