I use apache jena fuseki as server sparqlendpoint interface for execute query sparql on an ontology OWL that is loaded on server apache jena. The queries are executed through python languages.
I have need that the results of query must be the consequence of process the reasoning.
How I do at configure the reasoner with apache jena fuseki?
I use library sparqlwrapper for SPARQL Endpoint interface to Python.
# defines the URI of the endpoint and the query to send
uri
="http://localhost:3030/Hotel/query"
query
=("PREFIX : <http://www.semanticweb.org/ontologies/Hotel.owl#> "
"SELECT ?hotel ?price WHERE {"
" ?hotel a :Hotel. "
" ?hotel :hasPrice ?price }")

# obtain a connection to the endpoint and sends the query
sparql
=SPARQLEndpointInterface(uri)
rs
,fields = converter(sparql(query))And this is the define the function sparql:
def __call__(self, statement):
'''
This function sends the query to the SPARQL end-point.

:Parameter:
statement: query in string form to send.

:Returns:
resultset: the result-set list in JSON format.

'''

resultset
=[]
self
._sparql.setQuery(statement)
self
._sparql.setReturnFormat(JSON)
print("SPARQLInterface is executing the query...")
try:
t0
= time()
rs
= self._sparql.query()
tf
= time()
resultset
= rs.convert()
print("Query has been executed successfully!\nTime elapsed: {0:.3f} seconds.".format(tf-t0))
except:
raiseException("")
self
._sparql.resetQuery()
return resultset
