Most modern geophysical models can be connected to the '''JEDI''' framework, provided that the following predefined abstract C++/Fortran '''classes''' or '''building blocks''' are coded:

{| border="1" cellspacing="0" cellpadding="5" align="center"
!CLASS!!Description
|-
|'''ErrorCovarinace''' || Background error covariance, training, and modeling ('''SABER''': BUMP/NICAS)
|-
| '''Field/Fields''' || Elemental operators to manipulate a field or a set of fields to the model state/increment vector and metadata
|-
| '''Geometry''' || Application grid definition, including coordinates, metrics, parallel decomposition, and operators
|-
| '''GeometryIterator''' || Methods to set/get state fields over specified grid points in '''LETKF''' applications
|-
| '''Increment''' || Procedures to operate on the increment vector that extends/inherits from the '''Fields''' class
|-
| '''LinearModel''' || Initializes, run, and finalizes Tangent Linear and Adjoint model dynamical/numerical kernels
|-
| '''LinearVariableChange''' || Tangent/adjoint increment vector variables transformation from one field to another
|-
| '''Localization''' || Model Ensemble Localization ('''SABER''': BUMP/NICAS)
|-
| '''Model''' || Initializes, run, and finalizes the Nonlinear model dynamical/numerical kernel
|-
| '''State''' || Procedures to operate on the state vector that extends/inherits from the '''Fields''' class
|-
| '''Trajectory''' || Methods to process the Nonlinear trajectory that linearizes the tangent linear and adjoint models
|-
| '''VariableChange''' || Nonlinear state vector variables transformation from one field to another
|}

==Code Design==

Below is a diagram showing the interoperability mechanism for the '''Geometry Class''' that allows '''Fortran''' to invoke '''C++''' function and vice versa for '''C++''' to invoke '''Fortran''' procedures.
