 <div class="block">Specifies the relationship of a <a href="../cs/AbstractCS.html" title="class in org.apache.sis.referencing.cs">Coordinate System</a> to the earth.
  A datum can be defined as a set of real points on the earth that have coordinates.
  Each datum subtype can be associated with only specific types of
  <a href="../cs/AbstractCS.html" title="class in org.apache.sis.referencing.cs">coordinate systems</a>, thus creating specific types of
  <a href="../crs/AbstractCRS.html" title="class in org.apache.sis.referencing.crs">coordinate reference system</a>.

  <h2>Instantiation</h2>
  This class is conceptually <cite>abstract</cite>, even if it is technically possible to instantiate it.
  Typical applications should create instances of the most specific subclass prefixed by <code>Default</code> instead.

  <h2>Immutability and thread safety</h2>
  This base class is immutable if the property <em>values</em> (not necessarily the map itself) given to the
  constructor are also immutable. Most SIS subclasses and related classes are immutable under similar conditions.
  This means that unless otherwise noted in the javadoc, <code>Datum</code> instances created using only SIS factories
  and static constants can be shared by many objects and passed between threads without synchronization.</div>
