When you set out to arrange something, how do you decide where the pieces go? Is it based on what looks right to you, what you believe goes together, or what someone told you to do? Or maybe you let gravity or the alphabet determine the order?
Common examples of taxonomies include:
A few taxonomies in this book:
Now unload that same bag into a kitchen without rules for where things go. How much longer would it take you? How much more frustrating a task would it be? How much variation would you get when the next person unloads groceries?
For example, what if I had organized the lexicon in the back of this book by chapter, instead of alphabetically? This might be an interesting way of arranging things, but it would need to be explained, so you could find a term.
Because there are many words for the same thing, exact classifications can slow us down. For example, I recently tried to buy some zucchini at a grocery store. But it wasn't until the clerk in training found the code for "Squash, Green" that she could ring me up.
Classifying a tomato as a vegetable says something about what you know about your customers and your grocery store. You would classify things differently if you were working on a textbook for horticulture students, right?
When taxonomies are arranged hierarchically, it means that successive categories, ranks, grades, or interrelated levels are being used. In a hierarchy, a user would have to select a labeled grouping to find things within it. A hierarchy of movies might look like this:
Hierarchies tend to follow two patterns. First, a broad and shallow hierarchy gives the user more choices up front so they can get to everything in a few steps. As an example, in a grocery store, you choose an aisle, and each aisle has certain arrangement of products, but that's as deep as you can go.
These are all examples of sequences:
We use hyperlinks to allow users to jump between taxonomies instead of duplicating or moving content. For example, we might hyperlink the bolded words throughout this book. If a user clicks on one of them, we could take them to a definition in the lexicon. We're moving the user to the content instead of repeating it.
A typical grocery store has a hierarchical aisle system, a heterarchical database for the clerk to retrieve product information by scanning a barcode, and sequences for checking out and other basic customer service tasks. I was even in a grocery store recently where each cart had a list of the aisle locations of the 25 most common products. A great use of hypertext.
A typical book has a sequence-based narrative, a hierarchical table of contents, and a set of facets allowing it to be retrieved with either the Dewey Decimal system at a library, or within a genre-based hierarchical system used in bookstores and websites like Amazon.com.
