There is now a little sandbox project in openEHRs Github space that
you can fork and then play around with in order to learn collaboration
and versioning via Github at https://github.com/openEHR/Sandbox Please
have a look and test.
Later there will likely be other more serious sub-projects under the
https://github.com/openEHR/ umbrella, e.g. various software projects,
specification source files and perhaps source files for parts of the
openehr web and experimantal knowledge repositories.
Regarding software we'll have mail discussion on the implementers list
(openehr-implementers@...) regarding criteria (licenses,
sustainability etc) for moving projects from private repositories to
the openEHR space, so please join that mailing list if you are
interested in contributing to the discussion. Whatever criteria we end
up with will then be discussed with the openEHR board.
