This is one of my students :smiley: doing our Clinical Database Design with openEHR course. He is trying to use Rails to solve an assigment, but I’m not a Rails expert, so anyone with Rails knowledge might help him better than me.

Hi Ian,

i added a comment. It needs tricky codes to implement COMPOSITE patten

The following example on GitHub is an extract of my project.

I will feedback recent experience to openehr-rails repository, until
the next medinfo.
