   * This opens the **Property Editor** dialog window.
4. Give the property a name: *Publication Date*.

   * Always try to add a meaningful description to help your editors.
6. Select **Select Property Editor** to specify what type of data is being stored.
   * Select the **Date Picker** icon since we need a standard date.
