if you get an empty result set and no error, maybe the resource is not
in the data store?
The query
"Select distinct ?s where{?s ?p ?o}."
list all resources in the store.
And maybe it is a problem because you don't use a URI.
Resources should look like <http://world.org/europe/Germany_2123>

You can create a resource with URI Germany_2123 (the API does not URI
resolution). But in SPARQL <Germany_2123> is a relative URI and will be
resolved against the base. It will not be Germany_2123
Then the subject will not match and as Stefan says, no results.
