You can import business rules from IBM® Operational Decision Manager and retrieve them from an IBM Operational Decision Manager repository, or a local application, library, or integration project, at run time.
Read the concept information about business rules in Business rules.
After you import a rule application archive into IBM Integration Bus, you can extract the schema files from it. You can use the extracted schema files to set parameters on the DecisionService node. You might also want to extract the schema files, for example, to create a wrapper schema for use with validation or mapping of the input message.
