Metadata Extensions Overview

Metadata Extensions Overview

PowerCenter allows end users and partners to extend the metadata stored in the repository by associating information with individual objects in the repository. For example, when you create a mapping, you can store the contact information with the mapping. You associate information with repository metadata using metadata extensions.
PowerCenter Client applications can contain the following types of metadata extensions:
  • Vendor-defined.
    Third-party application vendors create vendor-defined metadata extensions. You can view and change the values of vendor-defined metadata extensions, but you cannot create, delete, or redefine them.
  • User-defined.
    You create user-defined metadata extensions using PowerCenter. You can create, edit, delete, and view user-defined metadata extensions. You can also change the values of user-defined extensions.
All metadata extensions exist within a domain. You see the domains when you create, edit, or view metadata extensions. Vendor-defined metadata extensions exist within a particular vendor domain. If you use third-party applications or other Informatica products, you may see domains such as Ariba. You cannot edit vendor-defined domains or change the metadata extensions in them.
User-defined metadata extensions exist within the User Defined Metadata Domain. When you create metadata extensions for repository objects, you add them to this domain.
Both vendor and user-defined metadata extensions can exist for the following repository objects:
  • Source definitions
  • Target definitions
  • Transformations
  • Mappings
  • Mapplets
  • Sessions
  • Tasks
  • Workflows
  • Worklets
