For example, grapeVine offers a series of starter templates optimized for specific industries. No matter which approach is employed to determine the taxonomy's lexicon, shooting for perfection could result in disaster. Simplicity and practicality are at the core of effectively rendered taxonomies. Broad, flat taxonomies are more effective than deep vertical ones, for example. And a straightforward classification scheme as opposed to an obtuse one will make users much happier.
People shy away from time-consuming and complicated systems.
But you have to remember that a good taxonomy should describe a reduced set of attributes so that it's meaningful to everyone. You can do amazing things with five or six attributes, each one of which has 20 values or so. The same held true for Coombs' project. He and his group were pushed to comply with the State of Washington's information indexing standard, but instead they landed on their own narrow set of indexing terms. Washington covers nearly any type of state or local government information imaginable, the public-facing taxonomy has only 25 categories.
