The Dexter Hypertext Reference Model is a formal and informal framework designed to capture the key abstractions found in various hypertext systems. The model aims to provide a principled basis for comparing and developing interchange and interoperability standards. It is divided into three layers: the storage layer, the run-time layer, and the within-component layer. The storage layer focuses on the network of nodes and links, while the run-time layer handles user interaction, and the within-component layer covers the content and structure within hypertext nodes. The model emphasizes the storage layer and the mechanisms of anchoring and presentation specification that connect the storage and run-time layers. The Dexter model was developed through workshops involving representatives from major hypertext systems, aiming to standardize terminology and provide a common foundation for understanding and comparing hypertext systems. The article also discusses the challenges of defining terms like "node" and the need for presentation specifications to handle dynamic content. The model includes a simple storage layer model with components, links, and anchors, and a run-time layer model that focuses on component instantiation and user interaction. The authors acknowledge the early stages of the model's development and its potential for advancing hypertext interchange standards.The Dexter Hypertext Reference Model is a formal and informal framework designed to capture the key abstractions found in various hypertext systems.
