The ezkeyword datatype (Keywords)

Class eZKeywordType in kernel/classes/datatypes/ezkeyword/ezkeywordtype.php; identifier ezkeyword, listed in settings/content.ini [DataTypeSettings] AvailableDataTypes[].

What it stores

Its class names none of the standard columns; it stores its value elsewhere (a table of its own or another object). It is indexed by the search.

In templates

my_attribute stands for the identifier of an attribute of this type in your class:

{def $attribute = $node.data_map.my_attribute}
{if $attribute.has_content}
    {attribute_view_gui attribute=$attribute}
{/if}
{* the value as the datatype returns it (objectAttributeContent()) *}
{$attribute.content|attribute( show, 1 )}

The shipped template that shows it (attribute_view_gui), design/standard/templates/content/datatype/view/ezkeyword.tpl:

{* DO NOT EDIT THIS FILE! Use an override template instead. *}
{$attribute.content.keyword_string|wash( xhtml )}
{if is_set( $#persistent_variable.keywords )}
    {set scope='global' persistent_variable=$#persistent_variable|merge( hash( 'keywords', concat( $#persistent_variable.keywords, ', ', $attribute.content.keyword_string ) ) )}
{else}
    {if is_array( $#persistent_variable )|not()}
        {set scope='global' persistent_variable=hash( 'keywords', $attribute.content.keyword_string )}
    {else}
        {set scope='global' persistent_variable=$#persistent_variable|merge( hash( 'keywords', $attribute.content.keyword_string ) )}
    {/if}
{/if}

The shipped template that edits it (attribute_edit_gui), design/standard/templates/content/datatype/edit/ezkeyword.tpl:

{* DO NOT EDIT THIS FILE! Use an override template instead. *}
{default attribute_base=ContentObjectAttribute}
<input id="ezcoa-{if ne( $attribute_base, 'ContentObjectAttribute' )}{$attribute_base}-{/if}{$attribute.contentclassattribute_id}_{$attribute.contentclass_attribute_identifier}" class="box ezcc-{$attribute.object.content_class.identifier} ezcca-{$attribute.object.content_class.identifier}_{$attribute.contentclass_attribute_identifier}" type="text" size="70" name="{$attribute_base}_ezkeyword_data_text_{$attribute.id}" value="{$attribute.content.keyword_string|wash(xhtml)}"  />
{/default}

Override them for one class attribute in an override.ini.append.php with Source=content/datatype/view/ezkeyword.tpl and a match on attribute_identifier (see A template override).
