Hi Marco, Had a look to jena for another project and didnt evaluate it here for these reasons (happy to be wrong):
- dep stack was huge for only graph part (guava shade, some other uneeded commons etc, most being excludable but without guarantees in time) - it is not about DAG and therefore misses navigation methods (which is what I need in addition to "mutation" methods for the algo i want to impl) - it is not the goal of jena so API and core stack can evolve in an undesired manner To mention alternatives, spark, flink, beam, ignite for the few I can think about, have something not crazy but still this stack and API issues :(. This is how i ended up looking commons, to try to have something stable and dep free.
