Generally, linking rules are easier to use and more powerful than enumerated links. However, sometimes it is not possible to define a linking rule. If you cannot define a linking rule, you can use enumerated links to link objects. You can also combine rule-based links and enumerated links. Use both methods when not all objects comply with a linking rule. Define a linking rule for most objects and use enumerated links for the exceptions to the rule.

When you create or edit a custom resource, you can specify additional input files that contain enumerated links. Add or upload the enumerated links files on the

Enumerated Links

tab. You can specify multiple enumerated links files for a resource. Metadata Manager creates the links when you load the resource.
