Business application developers put a wealth of business knowledge into their code. Too often, aside from executing, that information is left untapped for knowledge purposes. In fact, well-designed code is ripe with valuable information that can be extracted directly from the code for use in a variety of knowledge-based technologies. That can have direct benefits for regulated industries, like Finance, that are faced with a growing burden to demonstrate proper management of their data. This presentation explores the implementation of an entire U.S. financial regulation to demonstrate how well-designed code can be leveraged to integrate with knowledge tools like semantic, data catalog, data lineage, audit, and graph technologies.
