Later phases of the GALEN Programme, during the late 1990s, have concentrated on robust implementations of GRAIL and the Terminology Server, development of the GALEN Common Reference Model in both scope and detail, and development of tools and techniques to enable the further development, scaling-up and maintenance of the model.
