[File] PRONOM signature conversions

[Gregory Lepore]

Greetings - for the past 5 years I have been working with the UK National
Archives to develop file format signatures for the PRONOM database. Those
signatures are very similar to those used by file. I have converted the
roughly 1,600 format signatures I've created to the 'file' format and
posted those signatures on my GitHub site at:

https://github.com/gleporeNARA/pronom-research/tree/master

The vast majority of these signatures are not currently being used by
'file'.

https://github.com/gleporeNARA/pronom-research/blob/master/formats.txt

lists an older set of formats that I have produced signatures for.

https://github.com/gleporeNARA/pronom-research/blob/master/'file'%20magic%20file%20from%20PRONOM%20sigs

is my collection of PRONOM signatures converted to 'file' format

https://github.com/gleporeNARA/pronom-research/blob/master/PRONOM%20to%20'file'%20test%20files

are the results of running file against my test corpus. As you can see,
most of the formats are not recognized.

In addition to the format signature I have sample files and a brief
writeup on each format.

I'm looking for help on how best to get these signatures into file.

Thanks!
