Hello! I have a problem with understanding Jena permissions. I have an application which creates named graphs, uploads and reads those through Fuseki. I would like to add some security and create different access rules for different users etc. As the documentation ( https://jena.apache.org/documentation/permissions/) says, it can be done with my own Security Evaluator implementation.
What I don't understand is where and how exactly permissions should be added. Should they be only at Fuseki side? If so, then how can Fuseki understand to process each model as secured model? If I wish to create secured model at the side of application, then I have to use this method: Factory.getInstance( SecurityEvaluator, String, Model ); which requires the SecurityEvaluator at the application side too. But if I add it there, then there is no sense in having the security evaluator at Fuseki side. My problem is that even though I added the permissions jar with my own SecurityEvaluator (a bit modified ShiroExampleEvaluator) to Fuseki correctly (with this example https://jena.apache.org/documentation/permissions/example.html), I cannot get it to process data through it. Fuseki is not seeing the incoming data as secured models. So, in short, the question is - how to set up Fuseki in such way, that it would see all incoming models as secured models and check the access level for those? And if it is impossible, what is the right way to add the permissions?
