Ember CP Validations is an Ember.js validation framework that uses computed properties for form and model validation. It's designed for Ember developers who need robust validation capabilities without relying on observers, supporting features like nested models, asynchronous validation, and internationalization. The framework is particularly useful for applications that need to validate Ember Data models, components, or services while maintaining Ember's reactive programming patterns.
