# Create a Link Attribute (Master Data Services)

[!INCLUDE[appliesto-ss-xxxx-xxxx-xxx-md-winonly](../includes/appliesto-ss-xxxx-xxxx-xxx-md-winonly.md)]

  In [!INCLUDE[ssMDSshort](../includes/ssmdsshort-md.md)], create a link attribute when you want users to enter a hyperlink as an attribute value, such as `https://www.contoso.com`.  
  
> [!NOTE]  
>  When users enter a value for a link attribute, the string must begin with **https://** or an error will be displayed.  
  
## Prerequisites  
 To perform this procedure:  
  
-   You must have permission to access the **System Administration** functional area.  
  
-   You must be a model administrator. For more information, see [Administrators (Master Data Services)](../master-data-services/administrators-master-data-services.md).  
  
-   An entity must exist to create the attribute for. For more information, see [Create an Entity (Master Data Services)](../master-data-services/create-an-entity-master-data-services.md).  
  
## Attribute Information  
 For each created attribute, a row with seven columns is added to the grid. The following table describes the columns.  
  
|Column|Description|  
|------------|-----------------|  
|Status|The attribute status.<br /><br /> When you click Save, the ![Icon for updating status](../master-data-services/media/mds-statusicon-updating.png "Icon for updating status") image displays, indicating that the attribute is updating.<br /><br /> If there are errors when creating or editing an attribute, the ![Icon for error status](../master-data-services/media/mds-statusicon-error.png "Icon for error status") image displays.<br /><br /> Otherwise, the status is OK and the ![Icon for OK status](../master-data-services/media/mds-statusicon-ok.png "Icon for OK status") image displays.|  
|Name|The attribute name.|  
|Display Name|The attribute display name.|  
|Description|The attribute description.|  
|Display Pixel Width|The attribute width.|  
|Type and Properties|The type and data type information of the attribute.|  
|Enable Change Tracking|Specifies whether the attribute is enabled for change tracking and shows the group number in parentheses.|  
  
 When you click an attribute, the following information displays.  
  
-   **Created By**: The name of the user who created the attribute.  
  
-   **On**: The date and time when the attribute was created.  
  
-   **Updated By**: the name of the user who last updated the attribute.  
  
-   **On**: The date and time when the attribute was last updated.
