Why Conceptual Modeling?
A Case Study of A11y First Text Editor
This presentation reports how conceptual modeling can be used in building a text editor in order to ensure accessibility in the practice of content authors. The conceptual modeling process supports development of systems users easily understand, and it establishes terms naming objects, actions and attributes designers agree upon.
