For the three discovery patterns (simple, complex, mediated), consider expanding the phone book example. - You have simple discovery with a personal phone book where you keep contact information you have become aware of and feel is important. - A project or business unit often has a contact sheet of project participants/unit members for a limited but nontrivial number of individuals -- akin to the complex discovery - A large and more disconnected population (ranging from a large company to a city) refers to contact information in a central directory -- the mediated case I think this also works for a service population and indicates that you may always have all three levels because they address different purposes. Moreover, the benefits of the mediated approach "typically far outweigh[ing] the management issues" may depends on the number of services and the needs being addressed. Also, when talking about metadata, there may be a standard vocabulary or a mediated interaction among known metadata vocabularies.
