The Software Library is a secure directory that is the centralized repository of the definitive, authorized versions of the software that your organization manages. It is the physical source for your managed packages. Each package that is in the Software Library has a unique signature that helps to maintain the integrity of the data in the library.
In ITIL terms, the Software Library is equivalent to a Definitive Software Library (DSL).
Each package is associated with a software resource. A software resource whose packages are sourced from the Software Library is referred to as managed. A software resource whose packages are not sourced from the Software Library is referred to as unmanaged. For example, the packages of an unmanaged software resource might be on an unsecured network share or a local hard drive.
We recommend that you source all your packages from the Software Library.
