Safety assurance or certification is one of the most costly and time-consuming tasks in automotive, railway, avionics, and other safety-critical domains. Different transport sectors have developed their own specific sets of safety standards, which creates a big challenge to reuse pre-certified components and share expertise between different transport sectors. In this paper, we propose to use conceptual models in the form of metamodels to support certification data reuse and facilitate safety compliance. A metamodel transformation approach is outlined to derive domain or project specific metamodels using a generic metamodel as basis. Furthermore, we present a metamodel refinement language, which is a domain-specific language that facilitates simple refinement of metamodels. Finally, we use two case studies from the automotive domain to demonstrate our approach and its ability to reuse metamodels across companies.
