After analysis, no API extension is required.

For multiple file download, we can use the existing /access/datafiles endpoint: API Guide. This endpoint provides the option to download original or archival files.

For downloading all dataset files, we can use the existing /access/dataset/{id}/versions/{versionId}endpoint: API Guide. It is very similar to the previous one described, and also provides the option to download original or archival files.

The SPA can call the access API directly as it already does in other scenarios.
