Abstract
There are provided a content distribution system and a license management method for performing, in a collective manner, license management of a plurality of resources contained in contents. Each piece of content contains one upper-level resource (which is first referred to within the content), at least one lower-level resource (which can be referred directly or indirectly from the upper-level resource), one startup document and a license-corresponding document (which is an information file for performing, in a collective manner, license management of the resources contained in the content). The startup document contains at least upper-level resource reference destination information and at least one piece of license information for identifying view licenses required for viewing the resources contained in the content. In each resource, if link information for accessing other content is described, information for accessing the startup document of the other content is described.
