Lifecycle Data Requirements Guide

Second Edition (January 18, 2002)

The Lifecycle Data Requirements Guide (LCDRG) currently contains elements that were developed for the archival description portion of the records lifecycle. These elements were based in part on NARA's previous data standard, Data Elements 800 (DE 800). Additional elements will be added and current elements revised as projects are developed and completed.
