unfold: removing the barriers to sharing and reproducing prospective life-cycle assessment databases

Abstract

unfold is a Python package that allows reproducing life-cycle databases which partially build on a data source that cannot be shared. It produces data packages that contain the differences between the databases to share and the licensed data source. The data package also includes a metadata file describing the databases, the author, and other helpful information. unfold allows one to pack and unpack any databases from a single data package to ease the sharing and reproducibility of prospective or scenario-based life-cycle assessment databases.
