Informatica 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 your CONTACT information with the mapping. You associate information with repository metadata using metadata extensions.

Informatica 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/PowerMart. You can create, edit, delete, and view user-defined metadata extensions. You can also change the values of user-defined extensions.
