Define It
• Information: The common forms of knowledge artifacts we find around us
• Architecture: The art and science of designing structures.
• Information Architecture: The art and science of designing information structures.

Define It
• Organization, labeling, and navigation schemes in an information system.
• The structural design of an information space.
• Making web sites manageable and accessible.
• A new discipline bringing architecture and design to the “digital landscape.”

Divide It
• Organization systems: Creating indexes, taxonomies, associations, sequences, thesauri.
• Labeling systems: Choosing and organizing the way concepts will be named and pointed to.
• Search systems: Creating effective automated info retrieval systems.
• Metadata: Developing the schemas and other representations that encode the above.
• Navigation systems: The use of all the above to assist a person to get to what they need.

Divide It
• User study: Finding out what users know, want, expect, and need.
• Info ecologies: Discovering the way information works and interacts in the social system of the organization.
• Research and writing: Digging into and explaining the above to the organization.
• Structure creation: Creating and revising deliverables.• Negotiation and compromise: Getting the organization
to agree on the appropriate structures and their constituents.
• Testing and revision: Trying structures and revising them and trying again.

Delimit it
• Vs information design: ID is the sensory representation, IA is the logical representation
• Vs usability and Human Computer Interaction (HCI): HCI and usability are about the behaviors that are useful and wasteful in using computers.
• Vs user experience: UE is about the emotional reactions that an application inspires. Or maybe UE is the overarching concept that envelops IA and related studies.
• Software development: Implements the structures that an IA creates

Delimit it
• Vs content management: A CMS consumes the products of IA and manages their continued update
• Vs KM: KM depends on the structures of IA. Good IA is KM.
• Vs Web sites: The Web is what made IA so hot, but it is only the first stop.
• Vs Libraries and information science: IA came from library science but has moved on to embrace a world of other stuff.

Discussion: Classical and Modern IA
• Contrast the classical and modern approaches described by R&M on page 356
• When would you use one over the other?
• What is the essential difference between the descriptive and the prescriptive?
• Can the descriptive ever become the prescriptive?
