This workshop will give technical communicators a guided opportunity to develop a documentation structure, with the emphasis on doing justice to existing, unstructured content, rather than merely recreating the concept, task, and reference ‘holy trinity’ of topic types. Chris and Kai will outline basic principles of creating a taxonomy and an information model, drawing on cognitive science concepts like learning and mental models, to explain why standard topic types don’t always work, but why taxonomies do. They will also show how information models can be effective in making structured content easier to understand, and efficient for technical communicators to reuse. The workshop will give attendees practice at using physical media to turn unstructured content into structured documentation, at deducing and sketching out taxonomies based on existing content. Techniques such as card sorting may be of particular interest to attendees whose job roles touch on usability, user experience, or information architecture.
