I think most other people on the openEHR mailing list are working in or
with groups that are developing openEHR implementations.  The open
source Java implementation is at V1.0 rc3 but the readme says there is
still a lot to do, and there is no query language implementation last
time I looked, so you can store data but not query it, as far as I can
tell. All other openEHR implementations are closed-source/proprietary.

openEHR seems good in theory but I am an empiricist and like to try
things in practice. Frustrating!
