Understanding Context

Chapter 20. The Materials of Semantic Function

“When I use a word,” Humpty Dumpty said in rather a scornful tone, “it means just what I choose it to mean—neither more nor less.”

“The question is,” said Alice, “whether you can make words mean so many different things.”

“The question is,” said Humpty Dumpty, “which is to be master—that’s all.”

Elements

TO ADDRESS HOW INFORMATION ARCHITECTURE COMPOSES CONTEXT, we need to look at what materials the practice requires for designing environments. What are the elements that it uses—the bricks and mortar, studs and joists—that create the joinery of coherently nested places?

The material for information architecture is mainly the semantic function of language. Names, categories, links, and conditional actions are not just for organizing objects but for also establishing place and shaping systemic relationships for entire environments. We can distill these elements into three categories (Figure 20-1): Labels, Relationships, and Rules.

I’ve mentioned these in various forms in previous chapters, but bringing them together into a three-part list helps solidify them as a model.

These three items loosely correlate with the three levels in a model developed ...
