You are top:)
very helpfull 🙂
i understand everything when you reply:)
many thanks! 🙂
i have done what you said (http://localhost:3030/Trabalho/sparql)
and now the return error is:
SELECT * WHERE {
?sub ?pred ?obj .
} LIMIT 10
Error: SPARQL error: QueryBadFormed: A bad request has been sent to the
endpoint: probably the SPARQL query is badly formed.
Response:
b'Parse error: Lexical error at line 1, column 11. Encountered: \'32\' (32), after prefix
"rdf"\n'
That looks like a parse error in the query string becing sent.
Look in the Fuseki logs and see what query string it actually received.
There is space after the prefix name and before the : character.
Right:
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
Wrong:
PREFIX rdf : <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
thanks for everuthig

Hi
i am having some problems using a jupyter notebook to query a fuseki
localhost, can you help me?
If the dataset is called "Trabalho", the SPARQL endpoint would look like:
%endpoint http://localhost:3030/Trabalho/sparql
or
%endpoint http://localhost:3030/Trabalho/sparql
(I should have pointed this out in the first reply)
/#/ are the UI and server administration operations.
http://localhost:3030/#/dataset/Trabalho/sparql is returning a page saying
<strong>We're sorry but this app doesn't work properly without
JavaScript enabled. Please enable it to continue.</strong>

my fist error was puting <> in the endpoint.
but for
SELECT * WHERE {
?sub ?pred ?obj .
} limit 10
