<description>
This document describes the Multi-Order Coverage map method (MOC) version 2.0
to specify arbitrary coverages for sky regions and/or time coverages and potentially other dimensions.
The goal is to be able to provide a very fast comparison mechanism between coverages.
The mechanism is based on a discretization of space and time dimensions. The system is based on
the definition of a specific storage of the map coverage using predefined cells hierarchically
grouped which makes it easy to produce and use for exploring astronomical collections.
