Part 1 covers the need, principles, and variety of measurement standards and Part 2 provides examples of actual standards across many industries such as language codes and phone numbers. This book is extremely informative and easy-to-read (I like Joe's writing style), and I found myself laughing out loud at several points in the book most notably around beer and Mad Magazine's metric system. As a data analyst and modeler, one of my tasks is to work with the business to understand and document existing domains as well as new and improved enterprise/industry domains. I will use this book as a reference in this endeavor.
