Last week I took an action to write up the General Technique for SC 2.4.2 Providing a concept map. I propose that this technique should be deleted from the list of sufficient techniques for SC 2.4.2. A concept map (sometimes known as a graphic organizer, concept diagram, etc.) is a visual representation of relationships among facts, figures, ideas, etc. Its primary purpose is to aid understanding rather than navigation. (In fact there is a reference about concept maps/graphic organizers in the Technique Providing visual illustrations under SC 3.1.5.) I suppose a concept map might be helpful for navigation in certain cases-- e.g., an instructional Web site where a diagram of the relationships among the facts and ideas discussed in the content might also allow people to move through the material in a non-linear way. But I'm not sure it would be useful enough in enough different circumstances to justify being offered as a sufficient general technique for SC 2.4.2 (multiple ways to locate content). Thoughts?
