NIEM is a useful companion to Microsoft Dynamics 365 (formerly Dynamics CRM) because Dynamics 365 make it simple to standardize your data model and to rename objects such as entities, attributes, and field labels without programming. By using Dynamics 365, you have a mechanism to efficiently enforce naming conventions and update your data model as your solution evolves.
NIEM is available in XSD and Microsoft Excel formats, as well as in Unified Modeling Language (UML) tools. You can learn more about the NIEM model here.
