Long Term Retention

The Long Term Retention (LTR) Technical Working Group (TWG) is addressing the "grand technical challenges" of long term digital information retention & preservation, namely both physical ("bit") and logical preservation. A major component of the TWG's Program of Work is the creation of a logical container format, named the Self-contained Information Retention Format (SIRF), for the long-term storage of digital information.
