Version 3.0
SPDX 3.0 allows users to communicate information at a much more granular level without having to package it as "envelope" data. A key design principle in SPDX 3.0 is that all elements may be expressed and referenced independent of any other element. This independence is required to support a variety of content exchange and analysis use cases and makes it easier to communicate single elements of interest. The relationship structure has also been updated to be both more expressive and easier to understand compared to older versions of the specification.
