A process for rendering a user interface for launching content for publication using a content management system (CMS), includes: providing, over a network, an editor application enabling editing of entities stored in the CMS; providing, over the network, a launch application, wherein execution of the launch application renders the user interface for launching content for publication, wherein the user interface includes a reference tree providing a hierarchical visualization of reference relationships amongst the entities; receiving selection of a group of entities for publishing; and generating, responsive to the selection, an application programming interface (API) call to the CMS to trigger initiation of a validation process to validate each entity, without requiring separate API calls for validating each entity; and, wherein the validation process, once initiated, proceeds automatically without requiring said separate API calls to separately initiate publication of each of the entities in the group of entities.
