13.0 The NetCDF-4 Data Model
The netCDF-4 data model adds Groups and
User-Defined Types to the classic netCDF data model, but backward
compatibility is preserved.
- The netCDF-4 data model is also known as the Unidata Common Data
Model, because of an ongoing effort to identify a common subset of
netCDF, HDF5, and OPeNDAP data models to improve interoperability for
data providers and users.
- The UML representation of the netCDF-4 data model below highlights in red the additions to the
netCDF-3 data model, showing netCDF-4
is conceptually a set of simple extensions to the classic netCDF data model.
