How can I use SPARQL 1.1 to change the DBpedia ontology?



You can use SPARQL 1.1 (from your SPARQL 1.1 compliant application) to 
generate triples is a named graph local to your application, based 
solutions returned to you from the public SPARQL endpoint. 

Important typo fix. I meant to say:


You can use SPARQL 1.1 (from your SPARQL 1.1 compliant application) to 
generate triples *in* a named graph local to your application, based 
*on* solutions returned to *your app* from the public SPARQL endpoint.



I do this all the time when editing definitions (for classes and 
properties) oriented triples in ontologies.



Typical example, where I am adding missing rdfs:isDefinedBy, 
voca:defines, and wdrs:isdescribedby relations to an existing shared 
ontology.



Note: I am using Virtuoso as my SPARQL 1.1 compliant application (so I 
have the ability to grab data from any SPARQL endpoint and then use 
SPARQL 1.1 for local named graph scoped INSERT and DELETE operations):
