Hi Eva,

As Irene said, we don’t have a strong recommendation about what you should do 
since we don’t understand your environment. That said, there are some patterns, 
principles and practices that you might consider in making your own decision. 
They may or may not be important in your environment.

Keeping an EDG UI graph separate from the data structure/validation graph is 
not too far away from the MVC pattern. See 
https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller

There’s also the much more general notion of separation of concerns you can 
apply to graphs a bit differently than to program code, but the general idea 
holds. 

See https://en.wikipedia.org/wiki/Separation_of_content_and_presentation

See https://en.wikipedia.org/wiki/Separation_of_concerns 
<https://en.wikipedia.org/wiki/Separation_of_concerns>

The rate of change is usually different for various artefacts. For example, 
user requirements often drive regular change to property group assignments but 
the underlying ontology seldom changes once there’s a lot of data to manage.

Following these ideas often leads to adopting a graph (or ontology) 
architecture. For some customer projects, an ontology architecture document is 
an early formal deliverable so that everyone can follow the agreed approach 
consistently.

Due to the need to change graphs over time, I nearly always keep the graph that 
controls the EDG UI (e.g. property groups) separate from the data 
structure/validation graph. That’s true even for my own sandbox development. A 
really nice side benefit is that it’s also much harder to accidentally break an 
ontology when only meaning to change a bit of the EDG UI if you’re not editing 
the ontology graph.

Cheers,
David
