The LRA Interface Model Artefacts package contains the LRA Constrained Domain Models. Constrained Domain Models are Domain Models which have been constrained to satisfy precisely the information requirements of one or more specified use cases. Constrained Domain Models are therefore constrained specialisations of existing Domain Models and any instance of a Constrained Domain Model element is therefore an indirect instance of a more general Domain Model class (i.e. generalised class).
