Access control and obligations in the category-based metamodel - A Roadmap Sedar Olmez June 19th 2016 Abstract Obligations and its theoretical approach needs some extensive work in the realm of computer science, these protocols are implemented in almost all infrastructures we experience in our day to day lives. The access control security procedures use a specimen of obligations and countless models have been developed to try and ensure stability in computer security. In this survey I will convey the various aspects of obligations in computer systems, obligations and its influence on access control, Black’s dictionary and obligations in law, a link between publications on obligations and the constraints of obligations in computer science. 1
