<p>Although there are several attempts of embedding static content in events’ brochures and posters, the increasing need for flexibility and versatility of the content, leads to the development of a mobile application with an in-app dynamic content management system. In this context, DigiOrch is an ongoing research program where, a Content Management System is developed to organize all the digital material and maintain the appropriate connection to the analogical markers. Furthermore, a mobile application is developed that lev-erages this system using in app dynamic modules, which, by utilizing the augmented reality technology, presents multimedia data such as texts, photos, videos, and 3D Models to the end-user by “superimposing” them on mobile devices screen, providing extra additional information on any valid smart-leaflet.</p><p>The overall workflow of the in-app Dynamic Content Management System (DCMS) can be described as a group of modules that managing and copying content files from a remote infrastructure such as an ftp server or a local resource if network is missing, to the mobile device’s file system.</p><p>The in-app DCMS consists of 4 modules: The first module is the <i>parser</i>, which is responsible for reading a downloaded *.json file and creating content-linked objects. The second module is the <i>download</i> module which is responsible for downloading the overall content by iterating the content-linked objects, created by the previous module. The third module le is the <i>update</i> module that, by iterating the initial content file and the local file system, suggests whether a content update is necessary. The fourth module is the <i>loading</i> module, which is responsible for fetching the content on runtime to fill the content-holding components, such as 3D Models and UI photo galleries, of the AR scenes on runtime.</p>
