                           Preface

Modern large-scale physics experiments generate a huge data stream,
measured in at least hundreds of terabytes. The time of their active
operation can reach several decades, and the amount of accumulated
data can exceed one hundred petabytes. In this context, the issue of
active and on-going management of data throughout their life cycle is
very important and highly topical.
The data management covers all aspects of the data life cycle, includ-
ing acquisition, collection, and storage; then simulation, processing
and analysis; and finally, accessibility, dissemination (particularly
providing open access) and archiving as well as using data for educa-
tion and outreach purposes. Each stage has its own specifics, and in
general, they all involve the acquisition of new knowledge and sharing
of this knowledge with the scientific world.
The Fourth International Workshop on Data Life Cycle in Physics
(DLC-2020) held in Moscow, Russia, was devoted to discussing a
wide range of important practical issues related to data management
throughout their life cycle. The main focus was put on various aspects
of storing astrophysical experimental data and using deep machine
learning methods to analyze and process these data. The use of accu-
mulated data in education and knowledge dissemination issues were
also considered.
These proceedings include the 20 best papers selected for publication
by the scientific editorial group.
