About Attribute Handlers

Attribute handlers are used to generate a value or conduct a distinguished action that a stand-alone attribute doesn't bring about. Attribute handlers are available in a drop down menu in the New attribute view as illustrated below.

Special handler menu:

To function as intended, each attribute handler requires appropriate data type and appearance settings. You select the attribute datatype manually from the Datatype drop down. In this on-screen help, each special handler direction provides you information about the datatype requirements. The appropriate appearance settings are applied automatically for the handler after selecting it from the drop down.

Special handler Appearance settings:

Some special handlers are always available and may be used in any products (modules); these are called "Common" handlers. Other special handlers are specific to certain products and are only available if those products are licensed. This guide describes the functionality and limitations of each special handler, and gives instructions for configuring the handlers with attribute metadata. The special handlers are grouped by product, with common handlers listed first.

About Metadata

With the metadata settings, you can amend or alter the conventional behavior of an attribute. In order to work as intended, some handlers require certain attribute metadata settings. Other attributes, on the contrary, provide a possibility to extend their functionality with an optional metadata. binURL, for instance, is the required metadata name the HostName handler demands for Efecte Inspector scanning purposes. Again, the setting editable is an example of an optional metadata, with which you can control users' possibility to edit an attribute value through the user interface.

To add metadata to an attribute, select an attribute in the template tree pane of the Templates view. Then, click Attribute metadata on the display menu to open the Edit metadata view of the selected attribute illustrated in the following picture.

Edit attribute metadata view:

In this on-screen help, information on special handler includes the respective metadata requirements, if any. If the handler necessitates metadata, it is provided in a Required attribute metadata table provides proposals of a possible metadata values. Accordingly, an optional metadata is also presented in a corresponding table.

Notice that all metadata is case sensitive and thus it must be precise. In the metadata names, the first word is always lowercase, but all of the following words have an initial uppercase letter, for example, showCode. When defining metadata names by your self, such as template or attribute codes, always use an initial uppercase letter to separate words in a metadata name. Also, notice that the metadata values that are either on/off or true/false begin with a lowercase letter.

Typically, you use metadata when assigning special handlers to attributes, but you can also assign handlers to general attributes and folders. More about the metadata settings of general attributes and folders please refer to the Administration guide.
