Meta Data Concepts to Support a Net-Centric Data Environment
February 2005

ABSTRACT
The term metadata is often defined as "data about data" but that circular
reference does little to describe what constitutes metadata and how it is used.
Here, we will focus on metadata as conceived to support the concepts of a
service-oriented architecture and, in particular, as it relates to the DoD Net-Centric Data Strategy and the NCES core services; more specifically, what
types and structure of metadata are implied by current use cases, what
functions are implied to support creating maintaining, and using such
metadata, and what is implied about a metadata infrastructure that would
support such metadata and its related functions.
