Luciana Tricai Cavalini has contributed an ecore model implementation of the Multilevel Healthcare Information Modelling (MLHIM) Reference Model to our metamodel zoo.
The MLHIM specifications allow the development of interoperable, semantically coherent healthcare applications. See http://www.mlhim.org/ for more information on MLHIM.
Do you have an interesting metamodel to share? You could contribute yours too!
