Taxonomy For document management and email archiving, it is a high-level, hierarchical classification for documents and records that facilitates the management of recorded information throughout its life cycle. Its focus is on the purpose of information within and how it is used across the organization. Each organization requires a different taxonomy because each has unique processes, organizational configurations, core competencies, and histories.

TWAIN (Technology Without An Interesting Name) is a widely-used program that lets you scan an image directly into an application (such as WebSearch) where you want to work with the image or save the image as a business document. Without TWAIN, you would have to close an application that was open, open a special application to receive the image, and then move the image to the application where you wanted to work with it. The TWAIN driver runs between an application and the scanner hardware. TWAIN usually comes as part of the software package you get when you buy a scanner.
