A new Python package, processinghistory, has been released.

This package attaches small text metadata to a GDAL raster file, using GDAL’s arbitrary metadata API. The metadata is in the form of a dictionary of entries for things like the script which created it, a short description of what it is, and so on. In addition to that dictionary, there is also a copy of the history metadata for all the parent GDAL files that were inputs to creating the current file, so that the entire lineage is saved with the current file. This means the detail of its creation can be traced, even without access to the parent files.
