Meta Model

The Essential Meta Model, is a detailed, extensible, yet easy-to-use meta model for describing an enterprise from top to bottom. The Essential Meta Model is published as open source and is available for use in both the Essential Cloud and Essential Open Source.

Essential Open Source

Essential Open Source is entirely free to use under the GNU GPL License. The toolkit includes the Essential Meta Model, advanced tools for both capturing data and applying complex analysis to your architecture, and the Essential Viewer with interactive reporting.

Essential Cloud

All the features of Essential Open Source plus more, minus the hassle. The low-cost, cloud version of Essential provides the functionality of Essential Open Source but with a web-based interface, an enhanced security model, better user management and the ability to overlay business outcome based packs.
