propose a method of describing several rights(licenses) derived from major DRM systems, and its prototype system. Up to now, most DRM systems use each own attributes of rights, data expressions, and process of generating capsules. Therefore, in a case of digital content distribution service, it is difficult to manage the licenses which depend on the DRM systems. In order to solve the above problem, we try to integrate the description of rights(licenses) based on XrML. Our method enables the prototype system to express several licenses. We experiment with two functions of the prototype system which the method applies to : license registration and license issue. The result shows that the prototype system has a good performance.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"40","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告データベースシステム（DBS）"}],"bibliographicPageStart":"33","bibliographicIssueDates":{"bibliographicIssueDate":"2003-07-16","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"71(2003-DBS-131)","bibliographicVolumeNumber":"2003"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":19290,"updated":"2025-01-22T22:15:22.223926+00:00","links":{},"created":"2025-01-18T22:51:47.719060+00:00"}
