Abstract: Embodiments relate generally to ensuring version compliance for software products used within an enterprise. Generally, compliance is checked by comparing the number of actual uses of each product version to license information relating to product versions. An enterprise is compliant if use of a product version is covered by a license. License information and actual usage information are generally collected to allow for such a comparison. Information concerning license attributes such as downgrade coverage and/or license type may allow for a more accurate determination of the number of each product version ultimately available. Additionally, a rollup procedure may be used to apply updates to base licenses. Version compliance may be performed as a stand-alone feature, or it may be used in conjunction with an entitlement coordination framework to manage usage throughout the enterprise.
