Yet to date it is not fully clear how business rules can be used to model compliant business process models. In this paper, we show that deontic assignments can be used to formally model business protocols. Within the regulatory framework of a business protocol, participants have the autonomy to perform activities according to their own business policies. This can be modeled using reaction rules.enText/Conference Paper1617-5468
