The Levels of Adoption document is intended to supplement the Digital Library Federation / Aquifer Implementation Guidelines for Shareable MODS Records, released in November 2006 under the auspices of the DLF Aquifer initiative. The Shareable MODS Guidelines represent a record-centric view of Aquifer's goals, whereas it is often helpful to set priorities for metadata creation with a user- and use-centric view. The newly-released Levels of Adoption document describes five general categories of user functionality that are likely to be supported by following specific recommendations from the Guidelines. It attempts to provide additional guidance to MODS implementers in the planning process by documenting what sorts of functionality is possible when certain elements of the Guidelines are
followed."
