"Combining real-world experience with a veteran teacher's ability to communicate, Phil Gochenour's Information System Design Using TWiki demonstrates the basic principles behind any system design, whether it's a cookbook or a software company's wiki. Gochenour's book builds an information system step by step, starting with the building block of all information systems, the topic, and continuing through metadata, search, to usability. With sample code that can be used to construct a complete, usable system on the TWiki wiki platform, Information System Design Using TWiki will help you harness the power of the TWiki wiki."
"Whether you are looking for a way to learn the basics of information system design, or are someone who works with TWiki on a daily basis and wants a handbook and more extensive user's guide, this book is for you."

What is TWiki?
A leading open source enterprise wiki and web application platform used by 50,000 small businesses, many Fortune 500 companies, and millions of people. Learn more.
This is a relatively small book, it is nicely written and has a good flow. I am happy to see that the little known application feature of TWiki is explained in this book in easy terms, using real world examples. See also blog How to Create a TWiki Application.
