Within the context of the ITIL
framework, the Definitive Media Library is a secure repository in which an organisation's definitive, authorised versions of media Configuration Items
(CIs) are stored and protected. It should contain master copies of controlled software media that have passed appropriate quality assurance
checks, typically including both procured and bespoke
application and gold build source code
and executable

In conjunction with the Configuration Management Database (CMDB), it effectively provides the DNA of the data center
i.e. all application and build software media connected to the CMDB record of installation and configuration.
The Definitive Media Library (DML) is a primary component of an organisation's release and provisioning framework and service continuity plan.
