Not able to run latest Knora Version

[janCstoffregen]

Dear dhlab,
when I start and compile Knora as described on the README, it gives me the following error ( I only imported ontologies from your repository )

reStart

This happens on Mac and Ubuntu.

Thank you so much for your help.

The error message says:

None of the available repositories meet our requirements of id: knora-test, sesameType: owlim:MonitorRepository

Since #921, a GraphDB repository has to be of type owlim:MonitorRepository. This is set in the repository configuration file when the repository is created. Perhaps the Docker image dhlabbasel/graphdb-free hasn't been updated since then. @subotic ?

[janCstoffregen]

Dear dhlab,
Sascha found the fix.

In graphdb-free-knora-test-repository-config.ttl

rep:repositoryType "owlim:MonitorRepository" ; and
sail:sailType "owlim:Sail" ;

It works now and I would like to do a pull request, but I'd like to ask if this has to be included then in the following file as well: graphdb-free-knora-test-repository-config.ttl

[subotic]

I forgot about this use case. When graphdb-free is used, then according to the GraphDB documentation, the following settings should be used:

...
rep:repositoryType "graphdb:FreeSailRepository" ;
        sr:sailImpl [
            sail:sailType "graphdb:FreeSail" ;
...

To be able to know which setting to expect, we would need to have a distinction in application.conf.

I would thus suggest, to add graphdb-free and graphdb-se as separate values for dbtype (instead of graphdb).

[janCstoffregen]

sorry, I meant should it be included in this file as well: graphdb-free-knora-test-unit-repository-config.ttl

[janCstoffregen]

I can't estimate what your proposal implies, it would be nice to only set the variable for the db once though, in application.conf and the import scripts for example read this file and check which database you chose so that there is online one "init-knora-test-unit.sh" - file and not one for each database.

[subotic]

Yes, the init scripts are not very user-friendly. I'm working on a more user-friendly version here, but his will take some time though as this is a side project of mine with a low priority.

I'm refactoring the graphdb-free scripts so that they behave the same as the graphdb-se scripts. You would need to use the correct one, depending on which GraphDB version you are using.

[janCstoffregen]

I agree, it's not so important, just a little bit more convenient.

wip in #959

@janCstoffregen could you maybe try out the branch from #959 and see if it works for you?

[janCstoffregen]

When using the webapi docker image with the environment variable set to graphdb, this error occurs again.. I know how to change it, just for your information.

[subotic]

The supported graphdb types are graphdb-free or graphdb-se.

[janCstoffregen]

So I thought if you use the docker webapi, you still have to declare the graphdb variable so that this message does not occur...

but I get this message again, after executing

 ./graphdb-free-docker-init-knora-test.sh

and using the docker webapi

[janCstoffregen]

I set the variable in application.conf to graphdb-free, I meant the environment variable in the docker-compose file.
