The paper that Helena Haapio and I did on the fit between smart contracts and prose objects is now available on SSRN.
It extends the "Ricardian contract" paradigm of Ian Grigg that has been picked up by R3cev, Barclays and others.
At the same time, I started making prose objects - CommonAccord document solutions - as separate git repos. The fit is good - a git repo is a useful "punctuation" (@xmlgrrl) for a prose object. It follows in the footsteps of how coders collaborate.
