This paper gives a comparative survey of selected authorization languages
proposed in the literature. It attempts to classify authorization languages by
analogy with domain-specific languages. The languages are classified into
one of the following domains: (1) operating systems authorization, (2) database
authorization, (3) temporal authorization, (4) hypertext authorization, (5) certificate
authorization, (6) role-based authorization, and (7) computer supported cooperative
work authorization. For each domain, some prominent example languages are
described in an informal yet uniform way. Throughout the paper, comparisons
are made to highlight the similarities and differences between various languages.
