Jurgen Ziemer was an IBM Industry Models, Banking Data Warehouse Consultant for 6 ½ years, leading data architecture for the Bank compliance team since Basel II in 2003.

I converted from data modeling to ontologies three years ago. Using OWL, I can define business constraints as axioms of the class structure. Executable business rules can be formulated in defined classes and semantic web rules. Traditional architecture has all these components separately (RDBMS, ETL, rules engine …).
In Semantic Compliance® everything is a Triple.
