Information Architecture (IA) is the art and science of structuring knowledge (technically data), and defining user interaction s (also see use case).

In the context of Web design, information architecture is the organization of information to aid in information retrieval. A common example of this is the categorization of similar information into sections of a website, with those sections displayed in pages. Information Architects create a variety of project deliverables including Site Architecture Map s and Wireframes (also known as Page Schematics).

The modern practice of information architecture was first popularized by Louis Rosenfeld http://en.wikipedia.org/wiki/Lou_Rosenfeld and Peter Morville http://en.wikipedia.org/wiki/Peter_Morville , co-authors of Information Architecture for the World Wide Web (ISBN 1565922824, AKA "the Polar Bear Book").

Information architecture often has an emphasis on usability studies and testing for website compliance to community standards. The body that governs web compliance is the W3C (World Wide Web Consortium). The W3C attempts to create standards for general use by web programmers and is headed by Tim Berners-Lee http://en.wikipedia.org/wiki/Tim_Berners-Lee . Tim Berners-Lee is widely credited as one of the inventors of the World Wide Web.

An Information Architecture Design Document template might look something like this:

1. Goals
2. User Experience (with Appendix A: Competitive Site Analysis)
3. Site Content
   1. Content Groups by Labels
   2. Functional Requirements (with Appendix B: Content Inventory)
4. Site Structure
   1. Structure listing or summary
   2. Architectural graphical views (blueprints)
   3. Global and local navigation schemes (with and optional Appendix C: Site Structure Listing)

Information Architecture may well be viewed as an umbrella phrase, given its close resemblance to Information Technology, and all the catch-phrases IT conjures up. However, the term information architecture describes specialized skill set which relates to the management of information and employment of information related tools. It also has some degree of association with library sciences due to the nature of information relationships and management of information content. Many library schools teach information architecture as a part of their curriculum.
