The main use for me is for documentation purposes. It is very practical 
to take the owl model, import that into protégé and use the Jambalaya 
plugin to create a graphical representation of the entities and the 
links between them.
While I had hoped this would also be possible by experting the model in 
UML (using the xmi format), it seems this does not allow storing a 
graphical representation (at least not in the tools I looked at).

To a large extent, you could also do the reverse mapping, converting owl 
into a equanda domain model and this can then be used to build the 
persistence layer and user interface. The difference being that owl is 
more generic in (data) modelling capabilities but the domain model has 
specific features to add annotations about constraints and hints for the 
user interface.

In the equanda context, you have to keep in mind that it uses code 
generation, and thus a compilation step is necessary to move from model 
(be it owl or equanda's own representation) to a running program. At 
first guess this seems to be a constraint.

Apart from that, I think I need a better understanding of what you want 
to achieve to give proper feedback.

Kind regards,
Joachim
