A 3-Layer Model for Metadata

We present a 3-layer model for metadata of which the key component is CERIF in the middle, contextual, layer.  CERIF forms the lowest, most detailed level of metadata information that is common across research objects such as datasets.  Its richness of representation makes it a superset over many other metadata formats allowing their congruent generation from CERIF.  CERIF is used in42 countries and is an EU Recommendation to member States.
