I had a very interesting conversation with Vikram from infoMENTUM – The Enterprise Content Management Services team the other day. He has been working with complex taxonomies in large organisations for several years and was kind enough to pass on some very handy tricks of the trade. He is an advocate of relational taxonomies, particularly for global organisations who need to have one unified “corporate voice” but also need flexibility and localisation to serve the differing needs of particular regions and communities.
