Query Named Graph including imports

[Richard Nagelmaeker]

Hi All,

In earlier versions of EDG, we used Sparqlmotion to query a named graph including all of it's imports. 

In recent versions of EDG, SPARQLMotion is removed. So we wonder how we can query a named graph including it's imports?

The query is sent or triggered by an application and the response has to be in RDF/XML.

Anybody a solution for this?

Cheers,

Richard

Hi Richard,

What do you mean by “query” here? Are you talking about something like a SPARQL CONSTRUCT query? Or do you simply want to return a graph with all its imports in RDF/XML format?

Hi Richard,

Thank you for your question. I 've got a solution I think, see the query below:

construct
{
     ?s2 owl:imports ?o2 .
  }
where
{
  graph ?o
  {
    ?s2 owl:imports ?o2 .
  }
 
  {
SELECT ?o
{
  graph <http://some-named-graph/>
{
 ?s owl:imports ?o .
  }
}
  }}

This isn't the final query, but it does the thing I need, query all graphs in the imports.

Regards,

Richard

Hi Richard,

Here are some SPARQL queries that might be helpful:

Select all direct imports of <http://some-named-graph>:

    SELECT ?import
    WHERE {
        GRAPH  <http://some-named-graph> {
             <http://some-named-graph> owl:imports ?import
        }
    }

Select all direct and indirect imports of <http://some-named-graph>:

    SELECT ?import
    WHERE {
        BIND (ui:graphWithImports(<urn:x-evn-master:t1>) AS ?graph)
        GRAPH ?graph {
            <urn:x-evn-master:t1> owl:imports+ ?import
        }
    }

Return ALL triples from the graph <http://some-named-graph> as well as all triples from any directly or indirectly imported graphs:

    CONSTRUCT {

        ?s ?p ?o

    }

    WHERE {

        BIND (ui:graphWithImports(<http://some-named-graph>) AS ?graph)

        GRAPH ?graph {

            ?s ?p ?o

        }

    }

Return only the owl:imports triples from the previous query:

    CONSTRUCT {

        ?s owl:imports ?o

    }

    WHERE {

        BIND (ui:graphWithImports(<http://some-named-graph>) AS ?graph)

        GRAPH ?graph {

            ?s owl:imports ?o

        }

    }

Hope that helps,

Richard C

Hi Richard,

 

Thanks for all the suggestions. Will use the ui:graphWithImports function to get the list of named graphs.

 

Thanks,

 

Richard
