4. I start Fuseki under Windows from the command line with this command:
%FUSEKI_HOME%\fuseki-server.bat --conf %MSRO_HOME%\fuseki_config.ttl
I've attached the fuseki_config.ttl file. It's rather long because I've found
that if a named graph isn't explicitly mentioned in the config file, it will
not be persistent, and I have to repeat these definitions for 9 databases. I'm
focused on the "prod" database only at the moment, so you can ignore the rest.
Also, I've tried deleting the config file definitions for the graph I dropped
(companies), but it made no difference.
5. I load the n-quads with this curl command:
curl -H 'Content-Type: application/n-quads' -w 'code=%{http_code}
connect=%{http_connect} bytes=%{size_upload} ##' -T /tmp/loadFuseki.2224.ttl
http://localhost:3030/prod/data
The tmp file has a .ttl extension, but in fact it contains n-quads. The
filename is generated by a script of mine.
I grep the output for "code" "connect" and "bytes". Code is 200 (success),
bytes=128456749, and connect is blank (no proxy). I am able to query the
triples just fine, but when I stop and restart Fuseki, they are gone.
What is greatly mystifying is that this problem seems to have started when I
deleted and recreated the database, but I had not changed the config file. Is
there something I have to tell fuseki, that it should persist triples, which it
had recorded in the previous database but is not indicated in the recreated
database?
Your help is greatly appreciated!

Subject: [EXTERNAL] Re: Fuseki Data Not Persistent
Hi,
can you add details on steps 4 and 5 please?
You're starting Fuseki with a configuration targeting a TDB1 database?
Or did you accidentally start it in in-memory mode?
How do you load the quads? Via SPARQL? Via CLI?
Cheers,
Lorenz
