Beyond Checksums: Conformance Checking as a Core Component of Authentic Digital Preservation

Thursday October 22, 2026 1:30pm - 2:30pm EEST

Education hall: Martynas Mažvydas National Library of Lithuania

Born-digital audiovisual collections increasingly enter archives with incomplete provenance information, heterogeneous production environments, and varying levels of technical quality. While checksum-based fixity methods reliably confirm bit-level stability after transfer, they do not reveal structural defects already present within files—defects that may affect authenticity, accessibility, and long-term preservation decisions.

This joint presentation brings together archival practice and tool development by the Austrian Mediathek and Jerome Martinez, developer of the MediaInfo project. From the institutional perspective, the Austrian Mediathek presents how systematic conformance checking was integrated into ingest workflows for born-digital audiovisual materials and how this reshaped internal assessment and decision-making processes. Based on the analysis of 4,771 incoming files, the archive identified internal inconsistencies such as truncated bitstreams, container irregularities, and mismatches between declared and actual data structures that remain invisible in traditional workflows.

Complementing this practice-based view, the MediaInfo developer introduces the principles behind the conformance checker, explaining how structural analysis at container and bitstream level makes such inconsistencies detectable and interpretable.

By combining operational archival experience with tool-level insight, the presentation demonstrates how conformance checking strengthens authenticity assessment, improves risk awareness at ingest, and supports informed, transparent preservation planning.

Conformance checking complements fixity by making structural integrity visible—turning stability into trust.
