Answer 1

Hi David,
Am done with the implementation i have some more quesitons for my understandings...
<item-descriptor name="category" xml-combine="append">
    <table name="dcs_category" type="primary" id-column-name="category_id">
           <property name="displayName" xml-combine="remove"/>
           <property name="displayNameDefault" data-type="string" column-name="display_name"/>
      <property name="displayName" data-type="string" writable="false" hidden="true" queryable="true" display-name-resource="displayName">
         <derivation user-method="atg.repository.dp.LanguageTranslation">
               <expression>displayNameDefault</expression> 
         </derivation>
              <attribute name="defaultProperty" value="displayNameDefault"/>
               <attribute name="defaultLocale" value="en_US"/>
     <table name="crs_cat_cat_xlate" type="multi" multi-column-name="locale" id-column-names="category_id">
      <property name="translations" display-name="Translations" column-name="translation_id" data-type="map"  component-item-type="categoryTranslation"/>
    </table>
  </item-descriptor>
  <item-descriptor name="categoryTranslation" id-space-name="categoryTranslation">
    <table name="crs_cat_xlate" type="primary" id-column-name="translation_id">
      <property name="displayName" column-names="display_name" data-type="string"/>
     </table>
</item-descriptor>
Question 1:
i have highligted displayName why these property name is same/Unique why not different ?
Question 2:
How atg.repository.dp.LanguageTranslation identifies the second item descriptor categoryTranslation and gets the corresponding values ?
