Creating Metadata Extensions

You can create user-defined, reusable, and non-reusable metadata extensions for repository objects using the Designer. To create a metadata extension, you edit the object for which you want to create the metadata extension, and then add the metadata extension to the Metadata Extension tab.

If you have multiple reusable metadata extensions to create, it is easier to create them using the Repository Manager.

To create a metadata extension:

Open the appropriate Designer tool.

Drag the appropriate object into the workspace.

Double-click the title bar of the object to edit it. If the object is a mapping or mapplet, click Mappings > Metadata Extensions or Mapplets > Metadata Extensions.

Click the Metadata Extensions tab.

This tab lists the existing user-defined and vendor-defined metadata extensions. User-defined metadata extensions appear in the User Defined Metadata Domain. If they exist, vendor-defined metadata extensions appear in their own domains.

Click the Add button.

A new row appears in the User Defined Metadata Extension Domain.

Enter the following information:

Field	Description
Extension Name	Name of the metadata extension. Metadata extension names must be unique for each type of object in a domain. Metadata extension names cannot contain special characters except underscores and cannot begin with numbers.
Datatype	Select numeric (integer), string, or boolean.
Precision	Maximum length for string metadata extensions.
Value	For a numeric metadata extension, the value must be an integer between -2,147,483,647 and 2,147,483,647. For a boolean metadata extension, choose true or false. For a string metadata extension, click the Open button in the Value field to enter a value of more than one line, up to 2,147,483,647 bytes.
Reusable	Makes the metadata extension reusable or non-reusable. Select to apply the metadata extension to all objects of this type (reusable). Clear to make the metadata extension apply to this object only (non-reusable). If you create a reusable metadata extension for a transformation, the metadata extension applies to all transformations of that type (for example, all Aggregator transformations or all Router transformations), and not to all transformations. If you make a metadata extension reusable, you cannot change it back to non-reusable. The Designer makes the extension reusable as soon as you confirm the action.
UnOverride	Restores the default value of the metadata extension when you click Revert. This column appears only if the value of one of the metadata extensions was changed.
Description	Description of the metadata extension.
