An elaboration of concepts proposed in this issue.

Discussion: Licenses as partial orders

Many(/most?) licenses do not adhere to a strict total compatibility ordering; for example, one license may be more strict than another in one regard but less strict in another. This imposes some design constraints on our mechanism for checking compatibility between a package checkout and its dependency:

1. There is a shared, static set of licenses corresponding to valid SPDX identifiers.
2. There will be a shared set of requirements that all licenses impose.
3. Each license declares a set of ⊂ or ⊃ "compatibility" relationships to other licenses along the relevant "requirement" axes.
   • This is to say: each ⊂ or ⊃ corresponds to exactly one requirement.
4. Each package checkout declares at most one license.
5. Each package checkout consumes each of its dependencies in a particular manner, which activates some subset of the license

Preface

This document refers to at least three projects:

1. the pex packaging tool
2. the spack package manager
3. the pants build tool

This document was originally intended as a response to this pex issue, which describes one way to directly integrate dependency graphs into a package manager or build tool.
