Creating Reusable Metadata Extensions

You can create reusable metadata extensions for repository objects using the Repository Manager.

When you create a reusable metadata extension for any type of repository object, the metadata extension becomes part of the properties of that type of object. For example, you create a reusable metadata extension for source definitions called SourceCreator. When you create or edit any source definition in the Designer, the SourceCreator extension appears on the Metadata Extensions tab. Anyone who creates or edits a source can enter the name of the person that created the source into this field.

To create a reusable metadata extension:

In the Repository Manager, connect to the appropriate repository.

Choose Edit > Metadata Extensions.

The Edit Metadata Extensions dialog box opens.

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

Open the User Defined Metadata Domain.

Click Add.

The Add Metadata Extensions dialog box opens.

Enter the metadata extension information.

The following table describes the options available in the Add Metadata Extension dialog box:

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 any special character except underscore, and they cannot begin with a number.
Object Type	Type of repository object to which the metadata extension is associated. This can be a source definition, target definition, transformation, mapping, mapplet, session, workflow, worklet, or all of these objects. You associate metadata extensions with specific types of transformations. For example, if you create a metadata extension for Expression transformations, it is available for Expression transformations.
Database Type	Database type. The database type is required for source and target definition objects. You can select a single database type or all database types. Required for source and target definition objects.
Datatype	Datatype: numeric (integer), string, or boolean.
Default Value	An optional default 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, you can enter a default value of more than one line, up to 2,147,483,647 bytes.
Maximum Length	Maximum length for string metadata extensions. Required for string objects.
Client Visible	Specifies whether the metadata extension is visible in PowerCenter.
Client Editable	Specifies whether the value of the metadata extension is editable in PowerCenter. If you select this option, the Repository Manager grants Client Visible permission as well.
Share Read	Specifies whether the metadata extension is visible in vendor domains.
Share Write	Specifies whether the value of the metadata extension is editable across vendor domains. If you enable Share Write permission, the Repository Manager grants Share Read permission as well.
Private	Specifies whether the metadata extension is private to the domain in which it is created. The Repository Manager enables this option when third-party application vendors create vendor-defined metadata extensions.
Description	Optional description of the metadata extension.
