Consider collaboration with the National Archives (UK) PRONOM technical registry

PRONOM is a community-enhanced technical file format registration that leverages unique identifiers (PUID) and format signatures for the identification of file formats.

Consider collaborating with the National Archives to leverage the internal signature data and format information for model training and format identification workflow.

Example of a signature data page for DNG 1.7:
https://www.nationalarchives.gov.uk/PRONOM/Format/proFormatSearch.aspx?status=detailReport&id=2804&strPageToDisplay=signatures

PRONOM data evolves and could potentially be used as an ongoing source for training, pending collaboration w/the NA to make data programmatically available.

Start by reviewing the PRONOM overview and the linked DNG 1.7 signature page to understand the available format and signature data. Done would require an agreed collaboration with the National Archives and a defined, programmatically available data source for model training and format identification.
