  Successful collaboration involves sharing information. However, parties may
disagree on how the information they need to share should be used. We argue
that many of these concerns reduce to 'the copy problem': once a bit of
information is copied and shared, the sender can no longer control how the
recipient uses it. From the perspective of each collaborator, this presents a
dilemma that can inhibit collaboration. The copy problem is often amplified by
three related problems which we term the bundling, edit, and recursive
enforcement problems. We find that while the copy problem is not solvable,
aspects of these amplifying problems have been addressed in a variety of
disconnected fields. We observe that combining these efforts could improve the
governability of information flows and thereby incentivise collaboration. We
propose a five-part framework which groups these efforts into specific
capabilities and offers a foundation for their integration into an overarching
vision we call "structured transparency". We conclude by surveying an array of
use-cases that illustrate the structured transparency principles and their
related capabilities.
