Thanks for the revision.
The problem goes away by simply opening the post to edit it and then saving. Don’t know why the earlier save was serialized and the later one not.
Decided to correct the data rather than test for serialized when displaying this field.
Removed much of the tedium by writing a script to identify all posts with field $relationship[0] == “a:1:…” and including an edit post link. For posterity and anyone else finding a similar problem here is my code to be read in conjunction with above.
`<?php
if (!empty($relationship)) {
if ($relationship[0] != ‘None’) {
?><span class=”ewo-text”> and <?php echo $relationship[0]; ?></span><?php
if ($current_user->display_name == ‘Administrator’) {
if (substr($relationship[0], 0, 4) == ‘a:1:’) {
?><span class = “ewo-error”>(Will Id = <?php echo $will_id[0]; edit_post_link(‘edit’, ‘ ‘, ‘.’, $id); ?>)</span><?php
}
}
}
}`
By way of explanation, the edit link appears only to the ‘Administrator’ user, the will_id is displayed for confirmation and the ‘None’ role is not displayed, useful for me but irrelevant in general. the a:1: is appropriate only for a single term.

Thanks for the suggestion, but inserting that code made no difference. Using:

if ( is_serialized($relationship) ) {
    ?><p>serialized</p><?php
    $relationship = unserialize($relationship);
} else {
     ?><p>Not serialized</p><?php
}

indicated that the data was not serialized.
Any further thoughts?

Apologies for not being consistent and including code from elsewhere. The following php code will list all terms and descriptions from all public and custom (not built in, i.e. excluding categories and tags) taxonomies:

$args=array(
  'public'   => true,
  '_builtin' => false

  );
  $output = 'names'; // or objects
  $operator = 'and'; // 'and' or 'or'
  $taxonomies=get_taxonomies($args,$output,$operator);
  if  ($taxonomies) {
    foreach ($taxonomies  as $taxonomy ) {
      echo '<p>'. $taxonomy. '</p>';
      $terms =get_terms($taxonomy, array('hide_empty' => 0));
      $count=count($terms);
      if ( $count > 0 ) {
        echo "<ul>";
        foreach ($terms as $term) {
          echo "<li>" . $term->name . ": " . $term->description . "</li>";
        }
        echo "</ul>";
      }
    }
  }
