AN ACCESS DEFINITION AND QUERY LANGUAGE TOWARD...

In this work we suggest a meta access control model emulating established access control models
by configuration and offering enhanced features like the delegation of rights  ego-centered
roles  and decentralized administration. 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.
