# Current status of data center for cosmic rays based on KCDC

## TL;DR

This paper discusses the development and current status of the KCDC data center, which provides open access to cosmic-ray air-shower data from multiple experiments, enabling data aggregation and joint analysis.

## Contribution

It extends the KCDC platform to include data from various cosmic-ray experiments, facilitating integrated data access and analysis across different sources.

## Key findings

- Successful inclusion of Tunka experiment data into KCDC
- Enhanced data querying and merging capabilities
- Initial results demonstrate effective data integration

## Abstract

We present a current status of data center based on KCDC (KASCADE Cosmic Ray Data Centre), which was originally designed for providing an open access to the events measured and analyzed by KASCADE-Grande, a cosmic-ray experiment located in KIT, Karlsruhe. In the frame of the German- Russian Astroparticle Data Life Cycle Initiative we extend KCDC in order to provide an access to different cosmic-ray experiments and make possible aggregation and joint querying of heterogeneous air-shower data. In the present talk we discuss the description of data and metadata structures, implementation of data querying and merging, and first results on including data of experiments located in Tunka, Russia, in this common data center.
