Hi @eric - I think it’s worthwhile for you to consider the progressed version of the MEDIC CR. It is part of a new open source initiative: http://santesuite.com/index.html#. The same dev team is behind this new effort.
Re OpenEMPI, I agree that we need to be clear about what are the licenses of the solutions we’re touting as OpenHIE conformant. I’m not sure, though, that these all need to be FOSS offerings. This topic is on the agenda for the OpenHIE Architecture 2019-06-10 call on Monday, I believe.
