+=head1 NAME
+
+BSE::CustomData - mix in for treating a field of a table as JSON.
+
+=head1 SYNOPSIS
+
+  package YourTable;
+  use parent 'Squirrel::Row', 'BSE::Custom';
+
+  sub columns { ... custom_data }
+
+  my $item = YourTable->getByPkey(...);
+  $item->set_custom($name => $value);
+  my $value = $item->get_custom($name);
+
+=head1 DESCRIPTION
+
+A simpler, cheaper alternative to the table metadata system, intended
+for uses where that would be far too heavy.
+
+Expects your class to define the following methods:
+
+=over
+
+=item *
+
+set_custom_data($value) - sets the custom data field in the row object.
+
+=item *
+
+custom_data - retrieves the custom data field in the row object.
+
+=back
+
+The data should be stored/retrieved as a BLOB, though JSON column
+types may also work.
+
+Provides the following methods:
+
+=over
+
+=item *
+
+set_custom($name, $value) - set the given field in the custom data to
+C<$value>.  C<$name> must be a simple string.  C<$value> must be a
+JSON compatible structure, including strings, numbers, arrays, hashes,
+and may not include blessed objects.
+
+=item *
+
+set_custom_all($hash) - set the entire custom data to a given hash,
+used by set_custom().
+
+=item *
+
+get_custom($name) - retrieve a value set previously by set_custom.
+
+=item *
+
+get_custom_all() - get the custom data hash.  Used by get_custom() and
+set_custom().
+
