TAPE4D raw datasets: encrypted working archive

This repository holds encrypted copies of the source datasets used in the TAPE-4D project. They are kept here so that the owner's own servers can download them. Every data file is encrypted (OpenPGP symmetric, AES-256) and cannot be read without the owner's key.

Each dataset keeps its original licence and terms. This archive grants no rights to anyone and is not a redistribution of the datasets. To obtain a dataset, please go to its official source.

Layout

<dataset>/<source folder>/part-NNNNN.tar.zst.gpg   # about 10 GB of original files per part: tar | zstd -3 | gpg AES-256
<dataset>/<source folder>/files.tsv.zst.gpg       # encrypted index: type, part, size, path of every entry
<dataset>/<source folder>/SHA256SUMS              # sha256 of every encrypted file in the folder
MANIFEST.json                                     # every folder and part: members, sizes, sha256, completeness
restore.sh                                        # download, check, decrypt and extract one folder or dataset

The paths inside the parts are relative to the original data roots:

• disk0/{dynamic,static}/... holds the main training data.
• data_extra/{dynamic,static}/... holds the 19 extra datasets.
• raw/... holds the extra stereo and TartanAir material.

Part 00000 of a folder carries all of its directories and symbolic links. Hard links are kept within a part.
