"The Keyword Catalog is a hierarchical, controlled vocabulary composed of commonly used key words, synonyms and phrases. It is mainly aimed at stock photographers who wish to easily find appropriate keywords to tag their growing image collections. It covers a very broad sweep of subjects and is divided into 40 convenient main categories, subcategories, headings and subheadings. The keywords have been systematically arranged in order to make it as easy as possible to find the keywords and associated words. If a word is spelled differently in British English and American English (as in colour | color), both versions are included. You can load all of the categories into your keywording application or on a need to use basis in order to streamline the navigation. You can use the Keyword Catalog with Adobe Bridge, Photoshop Lightroom, BreezeBrowser Pro, Photo Mechanic, etc."
