The document discusses various tools and methods for representing information architecture (IA), including blueprints, wireframes, content mapping, content modeling, controlled vocabularies, design sketches, and web-based prototypes. It provides examples and guidelines for each method. Key tools include blueprints for site maps, wireframes for page layouts, content mapping for organizing content, and controlled vocabularies for standardizing terms. The goal is to effectively communicate the IA to audiences and production teams.
