Preston uses Apache Virtual File System (VFS) file path notation to point into (compressed) archives.
e.g.,

tar:https;//example.org/file.tar!/somefile.txt

references a file, somefile.txt inside a tar ball at https://example.org/file.tar .

for gzipped archives, VFS allows for both

tar:gz:https;//example.org/file.tar.zip!/file.tar!/somefile.txt

and

tar:gz:https;//example.org/file.tar.gz!/somefile.txt

But . . . when used in Preston for some reason,

tar:gz:hash://sha256/bf18509ad6a2a97143d4f74e72dc4177ec31a4c50b3d7052f9a9cf6735f65e43!/50418.1.1.tar!/0050418/1.1/data/0-data/NODC_TaxonomicCode_V8_CD-ROM/TAXBRIEF.DAT

does not resolve, even though the contentid and file path exists.
