The mandatory part of the Package information in SPDX Lite is basic but useful for complying with licenses. It is easy to understand licensing information by reading an SPDX Lite file. It is easy to create manually an SPDX Lite file by anyone who does not have enough knowledge about licensing information, so that tools are not necessarily required to create an SPDX Lite file.
SPDX Lite has affinity with SPDX tools due to its containing the mandatory part of the Document Creation and Package Information in the SPDX Lite definition.
An SPDX Lite document can be used in parallel with SPDX documents in software supply chains.
