This afternoon I led a session on DataPortability as it relates to HealthCare. The topic is expected to range over OpenId, OAuth, Microformats and other related projects.
This turned out to be a very lively discussion. PRivacy is a major concern but the idea is that there are a lot of developer eyeballs focused on standards like OpenID and OAuth that will address problems more quickly than with proprietary solutions.
This discussion will continue at the next HealthCamp.
