CoreMedia Studio supports server-side validation based on a project-specific configuration. To this end, validators are configured in the REST service web application. Validators can analyze content and report issues which are available at the client side as described in Section 5.3.3, “Issues”. Validators are implemented in Java and injected into the Spring application context of the web application. See Section 5.5, “Web Application Structure” for an introduction of the server-side architecture.
