Semantic Management of your Media Fragments Rights
The document discusses the importance of copyright management for digital media, highlighting the inadequacies of traditional digital rights management (DRM) systems and proposing a semantic technology approach for rights management. It emphasizes the need for interoperability and effective dispute resolution in the context of user-generated content and remixing. The presentation outlines a conceptual model for copyright that incorporates knowledge representation tools and semantic web principles to facilitate better management of media rights.
