A few days ago we released the new KCDC version PENTARUS, which contains another DataShop for the first time. A brief outline of the new features will be given here, as well as possible future perspectives.
We will introduce a data analysis extension for the KASCADE Cosmic-ray Data Center (KCDC), based on the Jupyterhub/notebook ecosystem. A user-friendly interface, easy access to data from KCDC, and modern analysis software are of special interest.
This contribution will discuss the service architecture, followed by a brief usage example.
The current state of the metadata catalog for astrophysics of cosmic rays is considered. The method of integration with external data storages is proposed.
