Part 5: Appendices
It is essential to note that all of the Views are graphical representations of what is
captured in an underlying data model. Therefore, individual instantiations of any
Views may differ. There are trends towards defining ‘Customised’ Views for
architectural frameworks that combine data in new and different ways, entirely
depending on the purpose. Therefore, creating View representation requires a certain
amount of creativity anyway, making small differences in View definitions negligible.
Thus, a full alignment cannot be expected, especially as details of each concept may
evolve and continuous full alignment becomes unmanageable. Currently, no further
alignment activities are planned. A key focus of any alignment task should be on the
meta-model (in line with current MODAF/DoDAF/NAF policies), rather than on
individual view descriptions. The MODAF HV meta-model may be considered as one of
the most developed HV meta-models, including a thorough alignment with existing
MODAF meta-model definitions. It may be noted that, rather than trying to align
similar HV concepts, it may be more beneficial to achieve a close link with the relevant
framework (e.g. MODAF, NAF), as part of which the HVs are to be applied. Only then
can HVs achieve their full potential.

Other differences lie in the way in which HVs were refined and applied, and what type
of practical guidance has been provided with them. The NATO HV has provided
important demonstrations of practical applications through concrete links with dynamic
modelling, where the focus of the modelling was to a large extent on providing a
structural representation of an enterprise (often ‘as-is’) that can be assessed to inform
the need for design changes. The MODAF HVs have put more emphasis on how HVs can
