Defining transformation rules to produce new facts from existing ones
Verifying data reported according to validation rules◦ Value assertions
◦ Existence assertions
◦ Consistency assertions
Documenting those rules Features:
◦ Business oriented
◦ Maintainable
◦ Extensible
The new Formulae specification

Concept filter = corep:CreditRiskCapitalRequirements
Concept filter = corep:MarketRiskCapitalRequirements
