In the diversifying information environment, contemporary hypermedia authoring and filtering mechanisms cater to specific devices. Display-agnostic hypermedia can be flexibly and efficiently presented on a variety of information devices without any modification of their information content. We augment context-aware Trellis (caT) by introducing two mechanisms to support display-agnosticism: development of new browsers and architectural enhancements. We present browsers that reinterpret existing caT hypertext structures for a different presentation. The architectural enhancements, called MIDAS, flexibly deliver rich hypermedia presentations coherently to a set of diverse devices.
