The legal call today had a clear focus at the junction of CommonAccord, blockchain, and UMA. The use-case was negotiation of a Non-Disclosure Agreement between two parties using CommonAccord as a structure for the changes that each of the parties would make as they passed the drafts back and forth. Blockchain was introduced as the non-repudiation mechanism to track the intermediate and final version of the NDA contract. UMA was not central to the discussion on the legal call today but was tacked on vaguely as the means to control access to the final contract by unspecified parties. It was not clear to me who the Resource Owner would be in the use-case we discussed. For the FutureCommerce hackathon, I'm hoping to gather a team to hack a personal UMA authorization server. This server, which I'm calling HIE of One http://hieofone.org/ could be linked to the CommonAccord project we discussed today to the extent there was a Resource Owner to associate with the contract being negotiated. At this point, instead of an NDA, the contract being negotiated in HIE of One is a Release of Information policy that establishes what requesting parties and clients can access the protected resource. An NDA is, in some sense, the opposite of a release of information agreement. An NDA is often mutual and therefore does not have a clear resource owner. This may not be a problem for some applications of UMA but it doesn't seem to work well for a personal authorization server linked to a personal resource. I'm hoping we could coordinate some of the FutureCommerce hacks over the coming week. Ideally, the CommonAccord hack and the personal AS hack would complement each other around the same type of contract and we could even try to demo some interaction between them. Please let us know your thoughts and consider joining FutureCommerce http://futurecommerce.civics.com/index.html online Nov 20-22. Anyone specifically interested in working on the personal AS hack should email me and I will invite you to the GitHub project. Adrian http://patientprivacyrights.org/donate-2/
