      AND = if permissive then lib.all else lib.any;
    in
    if license.licenseType == "simple" then
      predicate license
    else if license.licenseType == "compound" then
      if license.operator == "OR" then
        OR (x: evaluateProperty predicate permissive x) license.licenses
      else if license.operator == "AND" then
        AND (x: evaluateProperty predicate permissive x) license.licenses
      else
        throw "Unknown license operator"
    else if license.licenseType == "exception" then
      AND (x: evaluateProperty predicate permissive x) [
        license.license
        license.exception
      ]
    else if license.licenseType == "plus" then
      evaluateProperty predicate permissive license.license
    else
      throw "Unknown license type or legacy license"
