The founding goal of using standards within acquisition of distributed learning content and technology is to reduce cost in both current and future acquisitions and collaborative efforts across organizations. This document explores existing successful acquisitions and supplies that language as well as successful ways to implement best practices of standards and to identify mature standards (as a part of the ADL research portfolio, the Total Learning Architecture (TLA)). It provides a reference both by technical standard, the standards associated technology, and the standards associated use cases as tied to that technology. This document is intended to updated periodically.
