DDEX's works standards provide a suite of messages that give a uniform mechanism to enable companies to exchange information on claims of ownership of musical works embedded in Releases, and to request and to be granted licences for using
the such musical works that are embedded in Releases. The works notification and licensing standards are typically used by DSPs and/or record companies to request information on right share ownership claims and to licence s work from music rights societies and/or music publishers, and for such societies and publishers to provide information, licences and/or licence rejections. These processes are supported two core standards, one focusing on works licensing and one on work ownership notifications. These standards are highly inter-compatible and share a common ontology/data dictionary. Additional processes are currently being developed. Once this work has concluded, the DDEX Knowledge Base will be updated.
DDEX has also defined how to physically exchange such licence requests and grants, alongside supporting documentation, for the licensing of physical products in Canada.
