Query: Distributed data storage for modern astroparticle physics experiments   The German-Russian Astroparticle Data Life Cycle Initiative is an
international project launched in 2018. The Initiative aims to develop
technologies that provide a unified approach to data management, as well as to
demonstrate their applicability on the example of two large astrophysical
experiments - KASCADE and TAIGA. One of the key points of the project is the
development of a distributed storage, which, on the one hand, will allow data
of several experiments to be combined into a single repository with unified
interface, and on the other hand, will provide data to all participants of
experimental groups for multi-messenger analysis. Our approach to storage
design is based on the single write-multiple read (SWMR) model for accessing
raw or centrally processed data for further analysis. The main feature of the
distributed storage is the ability to extract data either as a collection of
files or as aggregated events from different sources. In the last case the
storage provides users with a special service that aggregates data from
different storages into a single sample. Thanks to this feature,
multi-messenger methods used for more sophisticated data exploration can be
applied. Users can use both Web-interface and Application Programming Interface
(API) for accessing the storage. In this paper we describe the architecture of
a distributed data storage for astroparticle physics and discuss the current
status of our work.
