Managing metadata | InfoWorld | Analysis | 2005-10-20 | By Jon Udell: "Everyone knows the common definition: Metadata is data about data, a secondary thing that's separate in some way from the primary thing to which it refers. But that definition begs a series of questions. Is metadata something we derive from data, or assign to it? Does it classify things, or enable us to search for things, or govern the behavior of things? If data that is described by metadata also, in turn, refers to other data, does it then qualify as both data and metadata?"
