A software model specification for a software package can be associated with representation of a software downgrade definition. The software model specification can include a publisher of the software package, an application title of the software package, and the version of the software package. One or more entitlements for the software package can be obtained. Based on the software downgrade definition being associated with the software model specification, the software downgrade definition can be associated with the entitlement(s). Compliance of the installations of the software package with the entitlement(s) can be calculated, where the software downgrade definition can cause each of the entitlement(s) to be applicable to the installations of the version of the software package or one or more earlier versions of the software package.
