This document discusses frameworks for classifying learning design representations and tools. It proposes a multi-dimensional framework with two key dimensions: degree of formalism and degree of abstraction. Different representation types such as textual, visual, and combinations are mapped within this framework based on their purpose and intended user. Examples of existing representations are also discussed and placed within the proposed dimensions to demonstrate how the framework can be applied. The framework is intended to help bring order to the variety of existing design representations and identify areas for further research.
