> How to load data and then start a fuseki server with that dataset and use it?
> -----------------------------------------------------------------------------
>
> Key: JENA-1930
> URL: https://issues.apache.org/jira/browse/JENA-1930
> Project: Apache Jena
> Issue Type: Question
> Affects Versions: Jena 3.14.0, Jena 3.15.0
> Reporter: Wolfgang Fahl
> Priority: Minor
> Attachments: fusekiscreenshot2020-06-26.png

>
> With my (unfortunately not successful) tdb2.tdbloader experience for wikidata
> I modified my script to load a smaller dataset like shown below (gnd2jena).
> The output log seems to be ok.
> {code:java}

> Now I am trying to run a fuseki server using the data like this:
> {code:java}
> #!/bin/bash
> # WF 2020-06-25
> # Jena Fuseki server installation
> # see https://jena.apache.org/documentation/fuseki2/fuseki-run.html
> version=3.14.0
> fuseki=apache-jena-fuseki-$version
> if [ ! -d $fuseki ]
> then
> if [ ! -f $fuseki.tar.gz ]
> then
> wget http://archive.apache.org/dist/jena/binaries/$fuseki.tar.gz
> else
> echo $fuseki.tar.gz already downloaded
> fi
> echo "unpacking $fuseki.tar.gz"
> tar xvfz $fuseki.tar.gz
> else
> echo $fuseki already downloaded and unpacked
> fi
> cd $fuseki
> java -jar fuseki-server.jar --tdb2 --loc=../data /gnd{code}
> Please note that I used version 3.14.0 here given that there where reports
> about 3.15.0 needing some kind of patching that i hoped to avoid by using the
> previous version assuming that the tdbstore would still be compatible or a
> message would show if not.
> At the servers port 3030 a user interface shows up showing that the server
> status is ok.
> !fusekiscreenshot2020-06-26.png!
> When clicking "Manage datasets" i get two options:
> * existing datasets
> * add new dataset
> None of the two buttons shows and effect. Clicking does not show any visible
> reaction. I would have expected I would be able to work with the imported
> dataset immediately (not even knowing whether you'd call the import a dataset
> ...)
> I already found some hint that I'd have to change the config.ttl manually to
> get the desired effect. I find it quite confusing that the web UI does not
> give any hints on this. I placed this as a question - not knowing whether
> this would end up as a feature request or bug ...
