Well that wasn't the question you asked! This is because updates go into the general dataset which is in-memory and non-persistent and not the persistent TDB dataset which backs the configured default graph
The workaround for that is to define two different services, one for query which uses the inference dataset and one for update that uses the TDB dataset directly and direct queries and updates to the two different services AFAIK there is no way to have a single dataset definition with your desired behaviour currently though I could be wrong Rob On 10/03/2016 10:55, "Maxim Kolchin" <[email protected]> wrote: >Hi Rob, > >Yes, it works that way (from [0]), but the problem is that newly >created named graphs (created with INSERT query) are not stored on the >disk, i.e. after restart the named graphs disappear. > >[0]: >https://github.com/apache/jena/blob/master/jena-fuseki1/config-inf-tdb.ttl > >Maxim > >On Thu, Mar 10, 2016 at 12:28 PM, Rob Vesse <[email protected]> wrote: >> You seem to have a circular reference in your setup so I am surprised it >> does anything at all >> >> <#dataset> references <#infModel> which references <#tdbGraph> which >> references <#dataset> >> >> So what I think is happening is that one of declarations is getting >>ignored >> >> If you look in the distribution you should see an example called >> config-inf-tdb.ttl where you can see how to configure this.
