A diagram depicting entities in the FIB-DM Loans & Mortgages package.

The package for data model objects derived from the Loans ontology module. This ontology is the top-level, and most fundamental ontology for the LOAN module, extending the Debt ontology to define concepts common to all loans. It includes the primary obligations to fund the loan and to pay it back according to payment schedules. Kinds of loans covered in this ontology include open and closed end, secured and unsecured.

Debt, Foundation, and other FIB-DM packages provide the Associative Entities connecting “island” entities like the Payment Schedule in this package diagram to the Loan.


The Card Accounts package diagram depicts the entities derived from the FIBO Cards ontology.

The consumer loans ontology defines concepts specific to loans offered only to consumers rather than organizations, primarily for personal, family, or household purposes.
A Consumer Loan breaks down into subtypes: unsecured and Secured Consumer Loans, currently Car and Home loans. The Consumer Loan has a Borrower, typically restricted to individuals. The Loan is collateralized by Physical Collateral (the car or house,) defined in the Finance, Business & Commerce/Debt & Equity package. An asset Pool, defined in the Asset Backed Securities package may have the Loan as a Constituent.
