Hi,
You’ve presented your system service configuration. We need to see the
configuration file
<http://jena.apache.org/documentation/fuseki2/fuseki-configuration.html> in:
$FUSEKI_BASE/configuration/text_svc.ttl
It is a ttl file that is interpreted by the assembler system to build the
endpoints and dataset components. This is where the jena-text configuration
info will go. Here is a sample configuration based on info in your service defn:
> # Fuseki configuration for BDRC, configures two endpoints:
> # - /bdrc is read-only
> # - /bdrcrw is read-write
> #
> # This was painful to come up with but the web interface basically allows no
> option
> # and there is no subclass inference by default so such a configuration file
> is necessary.
> #
> # The main doc sources are:
> # - https://jena.apache.org/documentation/fuseki2/fuseki-configuration.html
> # - https://jena.apache.org/documentation/assembler/assembler-howto.html
> # - https://jena.apache.org/documentation/assembler/assembler.ttl
> #
> # See https://jena.apache.org/documentation/fuseki2/fuseki-layout.html for
> the destination of this file.
