The suggested meta access control model is named ''Access Definition and Query Language'' (ADQL). ADQL is represented by a formal, context-free grammar allowing to express the targeted access control model, policies, facts, and access queries as a formal language.Towards a Unified Access Control ModelPolicyAccess Control ModelSecurityMeta Access ControlSonnenbichler Andreasauth1288604BOOK9910346860903321An Access Definition and Query Language : Towards a Unified Access Control Model3020908UNINA
