  Euclid is a Europe-led cosmology space mission dedicated to a visible and
near infrared survey of the entire extra-galactic sky. Its purpose is to deepen
our knowledge of the dark content of our Universe. After an overview of the
Euclid mission and science, this contribution describes how the community is
getting organized to face the data analysis challenges, both in software
development and in operational data processing matters. It ends with a more
specific account of some of the main contributions of the Swiss Science Data
Center (SDC-CH).
