Definite Media Library (DML)

HPE Service Manager refers to a Definitive Media Library (DML) in the Information Technology Infrastructure Library (ITIL) context. The DML was previously called the Definitive Software Library (DSL) in ITIL versions earlier than Version 3.

The DML is the secure, logical library in which the definitive authorized versions of all media Configuration Items (CIs) are stored and protected. The DML covers not only software, but also other types of media that require control, such as databases and files. The DML is a single logical storage area that can be linked to multiple locations. All software in the DML is under the control of Change and Release Management and recorded in the Configuration Management System (CMS).
