Thank you, Lorenz.
I did as you suggest and made the changes indicated.
Fuseki started and seems to have accepted the jetty config. But then when
trying to send the update the same error occurs and the limit seems unmodified
(I used2).

update payload to Fuseki2?
I don't know myself how to configure jetty, even less with Fuseki. I hope for
you somebody else on the list does.
Regarding LOAD however, you should be able to use HTTP URIs.

reak it. 500 is a general "internal error" code, it's
not specific to query length. It could be something else (look at the logs).
Did you try to run the query from the Fuseki web interface, or even with
another database entirely? It could help you debug it.

Can you share your query? I don't understand if you're trying to insert a
single literal string that is 85MB in size, or if you're trying to load 900K
triples that are 85MB in tot

Hi,
Maybe a long shot but thought I'd ask.
I'm sending updates to a Fuseki2 from an RDFLib/SPARQLWrapper based client.
This POSTs an INSERT string to an update endpoint. I get back an error 500 for
strings over a certain large size which (the limit) I haven't tried to figure
out.

Can't you simply use any any CONSTRUCT query on an inference model? Or
use an INSERT query to write it to a graph? Indeed bot only if you're
producing proper RDF triples.

Hello,
(I apologise for I am not sure if this has been addressed before and I have not
found the right thread or documentation.)
The configuration file below seems to allow reasoning with either a GRR or an
out of the box reasoner on the same dataset.
However, I don't think it allows combin

See last example in:

By the way, for simply getting code loaded into fuseki you don't need to
repack the jar. Just add your new jar to the classpath and use the
ja:loadClass function to get your class loaded when fuseki starts up.
See last example in:
https://jena.apache.org/documentation/fuseki2
m.add(a, q, "foo");
m.add(b, p, "FOO");
m.add(b, q, "foobar");
GenericRuleReasoner reasoner = new GenericRuleReasoner(Rule
.parseRules(rules));
InfModel infModel = ModelFactory.createInfModel(reasoner, m);
infModel.write(System.out, "Turtle");
}

As it says in the documentation, for examples of how to write particular
sorts of builtin then the best place is to look is the source code for
the current builtins.

Hi – yes, it works for me using fuseki as well. Apologies, I think my config
file was bad or the data somehow.
For reference, similar to your test:

rule reasoner

I am trying to:
Set up Fuseki2 with inference and a TDB2 dataset in which can be persisted

This is in order to:

- maintain datasets in a number of named graphs
- perform reasoning in the union graphs
