to combine several predicates used in filtering a graph? The idea is to have some predicates defined and arbitrarily combine them so that the filtered_graph will check for compliance of each individual predicate and either make this vertex/edge visible or not. Something like big_predicate = predicate1 || predicate2 || predicate3 (syntax should just illustrate the idea) maybe?

Have you considered Phoenix? (thought I'd mention it before OvermindDL1 this time)

Thank you. No, this is entirely new to me. I had a quick look on it and it definitely seems to be a possible solution. Because it is a quite broad topic and there are different things to take care of, do you have any particular topics that are covering solution to my intention (Actors, Operators etc.)? I am concerned actually about the type that such a combination of predicates might have, because the type has to be provided to the filtered_graph- template... Best, Cedric
