In a sentence, here's what's wrong with predefined ontologies and taxonomies: "we use existing patterns to search the data, which can't turn up new patterns." In another, here's what's wrong with manual tagging: "his department generates 5 million new objects per month, too much for manual tagging." Now if you take these two points as given, as I do, then what follows? How would you approach metadata and design?
