NMF

Round-tripping Metadata "NMF is designed to allow both a natural description of metadata in NMF while also allowing as large a subset of RDF metadata as possible to be translated into NMF. This translation between the NMF representation and the RDF representation must be supported in both a type aware and type unaware environment. In practice, even the type-aware (schemas available) environment may not have access to the type information for all of the metadata that the mapping is being applied to."
