OVUM have recently published a interesting research content management report titled, The corporate taxonomy: creating a new order by Eric Woods. The report is available online or as a PDF for members only.
This report discusses the importance of taxonomies in information management within a corporate environment and also, some of the areas to recognise as risks, ownership, costs, lifespan, etc. It also covers in further detail, structured and unstructured information management technologies, how to develop a taxonomy, the investment and resources required and of course the bigger picture.
