Linking rules are expressions that Metadata Manager uses to link matching objects across different resources. To run data lineage across metadata sources, you can define linking rule sets in linking rules files. Then, upload the files to the source or target resource configured in the file to create the rule sets in the Metadata Manager repository.
When you upload a rule set to a resource, Metadata Manager associates the rule set with the source and target resources identified in the file. If either the source or target resource does not exist, Metadata Manager still creates the rule set, but it is not valid. When you create the source or target resource, Metadata Manager associates the saved rule set with the resource and validates the rule set.
When you create or update a rule set, Metadata Manager does not create the links between the resources. To use the rules to link metadata objects between resources, you must load the resources or create the links in the
Resource Link Administration
window.
Use linking rules to create links between the following resource types:
Custom resource to another custom resource
Custom resource to a packaged resource
Custom resource to a universal resource
Custom resource to a business glossary resource
Business glossary resource to a packaged resource
Business glossary resource to a universal resource
To link matching objects between different packaged or universal resources, configure connection assignments in the
Load
tab. If connection assignments do not create all of the required links, you can also use linking rules to create links between the resources.
