# Before the Errata was introduced, the SPARQL query could be run
# directly against the DBPedia endpoint:
#
##echo "Downloading SPARQL query: countries-in-esc-by-year.sparql"
##./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.
