This website uses a parser done by Primavera De Filippi of Harvard's Berkman Center. It supports a "DRY," peer-to-peer transaction model, including with blockchain and UMA (pdf). There can be close coupling of "smart contracts" and contract text, enabling "Ricardian" contracts. A taste of the "experience" can be seen in this YouTube video. The vision was articulated in an OSCON interview with Slashdot. The files can also be expressed as JSON/IPLD.
