Hi all,
i try to run rdflib 5.0 with the SPARQLUpdateStore against graphdb from
ontotext (actually against their rdf4j RestAPI) .
Anybody knows how I could do SPARQL UPDATE queries with rdflib 5.0 against
their store.
Authentication works but i get an HTTP response code of 415 with message
"unrecognized mime type".
I assume it is because rdflib currently sends the data as byte string.
And it seems we would need the POST body to start with "update: INSERT ...".
Also i do not see that the Content-Type header field is set in the POST
request.
Looking at the removed SPARQLWrapper library is see that SPARQL update POST
queries can be encoded in two ways:
if self.requestMethod == POSTDIRECTLY:
request.add_header("Content-Type", "application/sparql-update")
request.data = self.queryString.encode('UTF-8')
else: # URL-encoded
request.add_header("Content-Type", "application/x-www-form-urlencoded")
request.data = self._getRequestEncodedParameters(("update",
self.queryString)).encode('ascii')
Best
Jürgen
