This article presents the idea of deening a kernel for object role modelling techniques, upon which diierent drawing styles can be based. We propose such a kernel (the ORM kernel) and deene, as a case study, an ER and a NIAM drawing style on top of it. One of the prominent advantages of such a kernel is the possibility to build a CASE-tool supporting(More)
