# Download the results of a query 
# e.g. all information about strikers in "La Liga"
# 1) let's start with looking at an example: http://live.dbpedia.org/page/Diego_Costa
#      ... here we find that Diego Costa play on position Forward, i.e.  
#    dbpedia:Diego_Costa prop:position dbpedia:Forward_(association_football) .
# and that his team is  
#     dbpedia:Diego_Costa dbpedia-owl:team dbpedia:Atl%C3%A9tico_Madrid .
# if we click further on dbpedia:Atl%C3%A9tico_Madrid ... we find that:
#  dbpedia:Atl%C3%A9tico_Madrid  dbpedia-owl:league  dbpedia:La_Liga . 
# 2) From this, we can forumlate a SPARQL query
#    to ask for strikers playin in La Liga:

   PREFIX dbpedia: <http://dbpedia.org/resource/>
   PREFIX dbpedia-owl: <http://dbpedia.org/ontology/>
   PREFIX prop: <http://dbpedia.org/property/>

   SELECT DISTINCT ?X ?T WHERE {
            ?X prop:position <http://dbpedia.org/resource/Forward_(association_football)> ;
            dbpedia-owl:team ?T .
            ?T dbpedia-owl:league  dbpedia:La_Liga .
    }  

# We can now send this query to live.dbpedia.org via curl:
# ... assuming the query is in the file  named 'strikers_from_dbpedia.rq'

 curl "http://live.dbpedia.org/sparql" -F 'query=@strikers_from_dbpedia.rq' -H 'Accept: text/csv'
