 ##./DBPEDIA-LOD-SPARQL-QUERY.sh countries-in-esc-by-year.sparql

+# Now a more complicated federated search is used.
+# Because the DBPedia endpoint doesn't allow for queries that
+# use SERIVCE to combine results from other endpoints, the
+# query we issue is done on the local Greenstone Apache Jena endpoint,
+# (which does have this facility on), where the Errata information is
+# stored, but as part of the query run reaches out to the DBPedia endpoint.
