I am a beginner to RDFs and I'm creating triples of the data with Ontotext Refine. I'm using the community edition of Ontotext GraphDB for viewing graphs. I created a RDF triple from the Fortune 500 dataset in the following
When I click the 'Open in GraphDB' button and run the SPARQL query generated, it returns the following result
Why is the prefix value not working, and showing the URL instead of the variable? Also, the URL code for the space is visible in the 7th and 8th row. The URL codes for ',' and '()' are also present. How can I remove them and replace them with their respective denotions? And last, the visual graph for this cannot be generated. It displays the error:
This node either does not exist or has no visible connections. Check your Graph Settings if you expect such
That's the entire error.
But when I convert the objects from literal to IRI, it displays the data
and the graph is generated as well
I emailed the support team a week ago but they have not provided any response.
