Very good call today. I was very interested in the discussion of templated consents. This seems very productive. If the consents are authored from templates and have GUIDs, then they can be made machine readable even if all the machine can read is the GUID (for instance in scanned PDFs, which I'm told are common). The GUID also provides a basis for notifications and permissions.
Here is a bit of old work that I did (Primavera did the diagrams) for the Global Alliance for Genomics and Health.
