Software Heritage — License Blob Dataset

Author: Stefano Zacchiroli

WARNING: you are looking at an old version of this dataset. A new version is available at: ../latest/.


This dataset contains all "license files" extracted from a snapshot of the Software Heritage archive taken on 2022-04-25. (A long-term archival version of this dataset is also available from Zenodo).

In this context, a license file is a unique file content (or "blob") that appeared in a software origin archived by Software Heritage as a file whose name is often used to ship licenses in software projects. Some name examples are: COPYING, LICENSE, NOTICE, COPYRIGHT, etc. The exact file name pattern used to select the blobs contained in the dataset can be found in the SQL query file 01-select-blobs.sql. Note that the file name was not expected to be at the project root, because project subdirectories can contain different licenses than the top-level one, and we wanted to include those too.


The dataset is organized as follows:

Changes since the 2021-03-23 dataset


A file name .tmp_1340d4e2da173c92d432026ecdc54b4859fe9911 was present in the initial version of the dataset (published on 2022-11-07). It was removed on 2022-11-09 using these two commands:

pv blobs-fileinfo.csv.zst | zstdcat | grep -v "\.tmp" | zstd -19 pv blobs.tar.zst| zstdcat | tar --delete blobs/13/40/.tmp_1340d4e2da173c92d432026ecdc54b4859fe9911 | zstd -19 -T12

The total uncompressed size was announced as 84 GiB based on the physical size on ext4, but it is actually 66 GiB.
