The Department of Defense Discovery Metadata Specification (DoD Discovery Metadata Specification or DDMS) is a Net-Centric Enterprise Services (NCES) metadata initiative. DDMS is loosely based on the Dublin Core vocabulary. DDMS defines discovery metadata elements for resources posted to community and organizational shared spaces. It is sometimes (incorrectly) referred to as "DoD Discovery Metadata Standard". The project focuses both on the process of developing a central taxonomy for metadata, and defining a way of discovering resources by their metadata using that taxonomy.
