How can I drop a graph for which is not clear was it created explicitly or not?

If you are not sure whether a given graph is created explicitly or not, in order to drop the graph use the DROP SILENT GRAPH statement:

DROP SILENT GRAPH <http://example1.com>

callret-0
Drop silent graph <http://example1.com> -- done

If a given graph is created explicitly however, i.e. using the CREATE GRAPH statement:

CREATE GRAPH <http://example2.com>

callret-0
Create graph <http://example2.com> -- done

then you can use DROP GRAPH in order to drop the graph:

DROP GRAPH <http://example2.com>

callret-0
Drop graph <http://example2.com> -- done
