Experiences using OCL for business rules on financial messaging

Abstract

In this paper we describe our experiences in using the OCL language in a commercial environment to validate XML-based financial data such as FpML [1] and ISO 20022 [2] data. We describe three problems we have encountered in supporting customer requirements when validating data in this context, and outline how we have chosen to support these requirements. We suggest that it would be useful to define a common approach to solving these problems for users of OCL.
