Trying to experiment with the interoperability through virtual graph by connecting multiple data sources.
Could able to see that we can combine multiple virtual graphs in the SPARQL query to get the required result.
But, if we need to combine data from multiple data sources (i.e.., 10 or 20) each connected to an different virtual graphs, hope it's not feasible to mention all the virtual graphs (10 or 20 graphs) in the sparql query .
So, is there any way we can create an implicit connected multiple virtual graphs in the backend and expose only a explicit single virtual graph (connected multiple virtual graphs in the backend ) to the consuming application so that there's no chaos in writing SPARQL query by mentioning multiple virtual graphs in a query ?
Could anybody please help on this clarification ?
