What are C24 Standard Libraries?

C24 Standards Libraries are specialised data model libraries and components for specific business scenarios, such as payments processing, OTC derivatives, and corporate actions. Each Standards Library implementation includes the industry standard message syntax, validation rules and test cases of valid and invalid data.
