ODRL allows to define policies which describe who is allowed to do what with a good. Despite its long history, ODRL 2.0 still has some drawbacks concerning the syntax and semantics of its entities and relations. This paper presents the results of an in-depth analysis of these shortcomings and outlines possible solutions. These include proposals to simplify the Core Model of ODRL to be better understood by new users as well as to prepare ODRL for the usage with encodings other than XML.enText/Conference Paper1617-5468
