Data model 2025

The last meaningful update to the LogiqX XML-based DAT format happened 28 October, 2008. Instead of modernizing an increasingly creaky standard, changes have been made ad-hoc by preservation groups and client applications to force new behaviors, resulting in the abuse of existing structures for unintended purposes, violating the standard, or the provision of sidecar metadata or services to enrich the DAT files to enable new use cases.

This site proposes a new datafile standard that's designed from the beginning to provide additional structure and metadata, so that DAT applications can implement extended functionality. Because the structure has been created conceptually and is still work-in-progress, it's likely it will need to evolve as applications are built that parse it and test its capability.
