[robinrj6]

User Story

1. As a user
2. I want to use a .7z compressed file
3. So that I can use FilePicker to access the .csv file from the compressed file

User Acceptance Criteria

• {acceptance criteria 1}

Examples

In the case of a dataset created as a result of a journal paper, the paper publishers may release all codes and intermediate data schemas together in a compressed file. 7z format being a lossless compression format, which helps to save space without any loss to the data, is widely preferred.

@robinrj6 Do you have an example data source?

[robinrj6]

This is the database I tried to download : https://figshare.com/ndownloader/files/37887318. This is a complete project code with datasets of different data schemes all compressed to .7z format.

Hey, thanks for pointing this out, seems like it would be great to support.

If anyone wants to take a stab at this, the extracting is done in the ArchiveInterpreter block and the implementation in the interpreter is here: https://github.com/jvalue/jayvee/blob/b20fcd91d70f5fd04982668f40d10953688c6653/libs/extensions/std/exec/src/archive-interpreter-executor.ts

We are using JSZip (https://stuk.github.io/jszip/) to extract zip archives in the interpreter, sadly it seems to not support 7zip.

In contrast, 7z does but is under GPL license: https://github.com/use-strict/7z-wasm?tab=License-1-ov-file.
