Sparql insert data not working

问题

I'm a newbie to Sparql, but I am unable even to make a simple insert data query, or so it seems.

I'm using Apache Fuseki as working server; I'm in a graph, and I'm trying to make this query work:

PREFIX oa: <http://www.w3.org/ns/oa#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>

INSERT DATA{             
  [ a 
    oa:Annotation ;                    
    rdfs:label "Title";                    
  ] .                    
}

But it doesn't matter what I do, I keep getting this error:

Error 400: SPARQL Query: No 'query=' parameter

This is even a semplified code, I tried many queries even more complex, but the result doesn't change...

回答1:

In SPARQL, query and update are different operations. In Fuseki, they reside on different endpoints (so query can be be more widely accessible than update).

You are calling the query endpoint (.../query or .../sparql usually) ; you need to call the update (.../update).

回答2:

There is a syntax error with your turtle in the SPARQL update

instead of

  [ a 
    oa:Annotation ;                    
    rdfs:label "Title";                    
  ] .     

use

  [ a 
    oa:Annotation ;                    
    rdfs:label "Title"                    
  ] .
