The Definitive Media Library (DML) in Serena Release Manager is a set of release vault baselines that are flagged as definitive media. Any baselines flagged as definitive media are considered ready for IT operations to release or distribute according to your organization’s processes.
Vault requests are used to introduce production-ready component sets into Serena Release Manager either directly as definitive media or to be tested as part of your organization’s defined testing stages and then flagged as definitive media.
In the default implementation of Serena Release Manager, baselines tested through the release vault in Serena Release Manager are automatically marked as definitive media upon deployment to the Production, or Live, stage.
